Doesn't matter...it's not a factor for AOS. The petitioner must file an I-864 and provide at leas the most recent year's tax return. A joint sponsor must do the same. It's the I-864 (I-865 is to report a change of address for an I-864 sponsor) http://www.visajourney.com/content/translations There's no "right" answer, but sending them before is probably better. We used separate folders for each form type. The check and cover letter was in front. Yes "Provide the beneficiary's address outside the United States, if different from Item Numbers 11.a. - 11.h. If the address is the same, type or print "SAME" in Item Number 13.a" AP is not required but highly recommended. Dates are not important..."As needed" is fine.

Are you already in the USA or planning to come?
VWP is for visiting the US, it is not for immigration and it is unlawful to use it in this way. You risk being turned away at POE if caught doing this (and lying to CBP is not advisable). Have your USC/LPR spouse petition for an IR1 spousal visa which you will receive from the embassy in your home country. Process is 12-14 months at present if married to USC. If you are already in the US, you are technically permitted to adjust status. Don't expect a lot of people here to be happy about that and offer much help, it's a touchy subject. I-864 (I assume you meant 864, as the 865 is for changing address) is only signed by the petitioner/sponsor.
 
Translations just need to be signed with a statement indicating that the translator is competent to translate from the specific language to English. USCIS says, "There must be a certification from the translator indicating that the translation is complete and accurate and attesting to his or her competence as a translator." See here.
 
Send pictures with your package.
 
Organizing everything is a matter of preference, but avoid stapling, and try to be logical. Also include a cover letter indicating what all is included, and list things in the order that you've included them. I used a lot of paperclips to divide forms, evidences, etc. Minimal burden to the officer reviewing, and ensured everything was easy to understand and not all run together.
 
Not sure about the last 2, I'm sure someone else can help out there.
 
 

My Case:
 
1) In my opinion, I think you better file it before your visa expired
 
2) I think the form just need your husband signature only (no need the other sponsor signature) (It's I-864)
 
3) I believe they need a translator who has a translation certificate? (Im not sure about that as I didn't use any translator) 
 
4) I did send some pictures as our bona fide marriage evidence 
 
5) for me i separate in 4 folders  (see the photo below)

6) there's an instruction for every form tells you if you need photos or not. but here is the numbers of passport photo (2x2') you need for the forms you mention:
I-130 (2 passport-style photos of the petitioner & 2 passport-style photos of the beneficiary;)
I-485 (2 passport-style photos of the beneficiary)
I-765 (2 passport-style photos of the beneficiary)
I-131 (2 passport-style photos of the beneficiary)
 
7) are you talking about the one in page 2? 
 
8) for me i just wrote "Unknown"
 
Hope it helps!
