Also I just noticed that you mentioned kids. I think its the same for each person i.e. they each need 2 for packet 3, 2 for the interview, etc. If you can I would do what Vanessa suggested and print them yourself to save some money- you're going to need it to pay for all the medical and interview fees.

Nothing like making someone feel stupid for asking a question!

No, the 864 is NOT necessary for the K1. It's on the checklist because the checklist is for CR1/IR1s as well as K1s. There is NO need to bring it, just the I-134. Most K1s here only bring the I-134s and its supporting evidence and it's fine.
You fill out the 864 when you adjust your status after you've entered the USA and married.

Before anyone else accuses Frostiana of not thinking this through I want to mention that unfortunately she had a badly informed lawyer that advised her to get a fiancee visa instead of a CR1 which would have allowed her to travel freely. It's really rude to accuse someone of not considering the consequences that go along with moving to a new country, especially when they have family to think about. If you don't find a website like Visa Journey to help you out the process can be very convoluted and confusing. Even so a lot of people don't want to leave their family/home/job to be with someone but they still do and it's not a decision that's made lightly. Everyone goes through this difficulty.
I would say your best bet is to get legally married ASAP and then do AOS. You don't have to have a wedding to get married of course- you just sign some papers, it takes like an hour to do. You don't have to tell anyone and you can always chose to celebrate your anniversary at a later date- it doesn't matter what the marriage certificate says, except for legal matters of course. My husband and I decided to do this because we got married the day before my birthday so I could take care of some business, but we're choosing to celebrate our anniversary on a different day.

Your belongings can either accompany you or arrive after you POE, but they cannot precede you, as others have noted.

Congrats!!!

Unfortunately there aren't many visa options available to you unless, as stated, an employer really wants to hire you over an american or you get married. Believe me I feel you... I think you are wise to not rush in and get married right away. My husband and I dated long distance for 3 1/2 years before we got married. It was NOT easy... sometimes I wondered why we were putting ourselves through all this, but for some reason we stuck with it. However, I am SO glad we waited before getting married because it allowed us to really get to know each other well and develop our trust (you have to believe that they're not doing anything behind your back if you don't see them for 3-4 months at a time!) And I believe the difficulty of the long distance relationship made us stronger because if we can manage that together, well we can manage anything
There is no easy answer to this kind of thing. Love is blind until you really get to know the other person well, if you're in a long distance relationship you have to have faith in the other person and also be a little crazy IMO. There is no definite way of knowing if its worth it or not until AFTER the fact...
So I suggest you continue seeing each other and plan long visits where possible until you're really sure it's the right decision. After a year of dating my husband long distance I was not okay with the idea of getting married. I wasn't after two years either. But after 3 years for some reason it clicked and it was the right decision.

Inky already posted everything that needs to be sent back with Packet 3. Packet 3 is a little confusing because one of the forms tells you to attach your birth certificate, police check, etc. but that is NOT the case. You ONLY send the forms that Inky listed plus two american style passport photos and a photocopy of the biographic information page from your passport. The checklist also addresses both K1s and CR1s so not everything on the checklist is required of you (most K1s don't need to bring the 864 for example, instead K1s do the I-134).
You DO NEED to submit the 156K and 156, as well as all the other forms Inky listed. A lot of other consulates don't require the same forms, that is why you see conflicting information, but the Montreal consulate requires the ones that Inky listed (you can view it on the Montreal consulate website as well.) Remember, USCIS only sets the minimum for what the consulates must require from you, but individual consulates can ask for additional stuff, so the procedure for every consulate is different! That is why its important to check the individual guidelines for Montreal, and to take advice from those with experience from Montreal.
The police certificate is valid for one year. I would suggest going to your local police station and asking about how to obtain one (an RCMP fingerprint check is not necessary unless you've been convicted of a crime) and how long it takes. You can read about the requirements for the police certificate here http://www.visajourney.com/wiki/index.php/Canada#Inside_Canada
For the medical you need to obtain your vaccination history. You can read about which vaccines are necessary here http://www.panelphysicians.com/Pages/Immunizations.htm You only need to get a chickenpox (varicella) vaccine if you didn't get chickenpox as a kid. If you don't have your complete vaccination records you should find them ASAP.
For HIV, they ask you verbally if you have it and they also take some blood samples from you. I don't know what they test with the blood samples but if you don't have HIV it's nothing to worry about because you just tell them you don't have it.

Oh and another weird thing I noticed- no one seems to take milk in their coffee here. At starbucks they only have half-and-half on their condiment counter, and at restaurants when I ask for milk for my coffee it comes in a small glass because they don't carry milkers. When I asked for milk for my coffee at one restaurant the waiter actually said "Uuuummm..." and seemed unsure if he could provide me with any. Isn't milk a basic ingredient? What the heck. I'm going to attribute that to the individual waiter because there's no way a restaurant can't have milk. That doesn't really bother me, I mean I can still get milk for my coffee and so far the servers here have been very nice... I just feel uncomfortable when getting milk in my coffee turns into a big production!

Well today marks one week since I got here. So far I love the weather (Las Vegas), our new apartment and the people (so far people have been very friendly and courteous... it's a huge difference from Brampton, ON). I had dinner with my fiance's family and enjoyed their company thoroughly.
Buuut one thing I can't get over is how terrible the grocery stores are compared to what was available in Ontario. Why is it so hard to find a large bag of chickpeas or lentils? So far I've been to Wal Mart, Smith's, Albertsons, and Food 4 Less and the only okay one in terms of variety so far was Albertson's, but it's expensive and is still lacking many of the things that I consider standard in my pantry... I miss being able to buy a big jar of tahini from Wal Mart for 4 bucks, and good multigrain breads and cheeses... The brie here is not that good. No Frills is loads better than Food 4 Less- sure NF has a lot of junk but it also had a lot of great healthy foods in bulk, like legumes and rice, and a good selection of produce. It seems like many of the grocery stores here are just aisles and aisles of junk food and pre made stuff. I don't want to sound like a snob but I make everything from scratch- hummus, soup, tomato sauce, beans, meats... Now it's more challenging and expensive. I shouldn't be despairing yet because we only checked out the grocery stores near by and I plan on hitting up an asian market soon in the hopes of finding more obscure things (like big bags of chickpeas? LOL!) at a decent price. I do not want to eat everything out of a box- my health is important to me, not to mention home made tastes way better!
My fiance always commented on how great the grocery stores are in Canada whenever he visited me. Now I understand why! Fortunately my fiance is a foodie like me and likes everything home cooked and healthy too, so this will be an adventure for us together...

Dad's Cookies (I don't think they're available in the States.)
Edit: Oh and Tim Hortons coffee if she likes that.

I think regardless of what's "bad" medicine, it can be agreed upon that these are professionals who should act and communicate with their peers and patients respectfully. Going into a tirade is inexcusable- getting mad does nothing to resolve the issue faster or more effectively. A patient trusts their doctor because their doctor went to school for a decade in order to help people, so it's not the patients fault if they're given bad advice- heck, in this case, the patient actually tried to do the responsible thing and locate their vaccination records but again was met with unprofessional conduct. Guilting a patient because of what another doctor told them to do is illogical, irrational, and frankly reeks of a lack of basic human decency. Likewise, getting upset at another doctor is completely unprofessional conduct. All the doctors in Canada make up a part of the health care system and should do their best to work together and with other health care providers even when they have disagreements.
Yelling at someone over the phone and pushing a patient to cry is disgusting behaviour even if Dr. Seiden was wrong. I mean, parents teach their kids not to yell and scream- we're adults aren't we?
Ehh, I know this isn't my argument, it just bothers me slightly because what ralyse has relayed to us thus far hasn't indicated that she was trying to do anything other than what she's supposed to do. That is, she tried to be prepared to the best of her abilities but due to circumstances beyond her control was met with some difficulties and then blamed for them. Ridiculous.
TL;DR A professional should not communicate his "feelings"- whether right or wrong- when trying to resolve an issue. A professional only cares about "righting" the wrong, and the best way to do so is calmly, respectfully, and efficiently. It's not by yelling. When someone yells at you do you listen? Yelling won't make and adult do anything differently- if anything, it'll make them more stubborn and resistant.
