This is all in the information provided to you earlier BUT, your fiancè will mail the package - everything together and the payment will be included in the package, check, money order both fine. You can sign, scan and email and he can print, but save all originals for your record.
 
The i-129f is only for the USC to sign...but other documents are for you. You really need to read and do your research. No one here can give you all the information in one post.

Slow down, take it step by step.  It is all in the guides here.
 
  There is a helpful thread pinned in the K1 forum.^^^

He is the American / he has to apply for you
You are the beneficiary and can not apply for yourself
He can get help to do this at Fort Bragg thru his commanding officer
 

Note that here is a specific address for sending through a courier such as FedEx or UPS. OP, these addresses are found on the uscis i129f link provided. Courier ofc costs more but is faster and easier to track than USPS (United States Postal Service). Personally don't trust USPS with anything important lol

Here are some  govt. website links
 
https://www.uscis.gov/family/family-us-citizens/fiancee-visa/fiancee-visas
https://www.uscis.gov/i-129f
 
Once the 129 F is completed he can mail it to:
 
File Form I-129F at the USCIS Dallas Lockbox facility:
For U.S. Postal Service (USPS):

USCIS
P.O. Box 660151
Dallas, TX 75266 .
 
Afterwards you wait til it is approved. Once approved the petition will be sent to the NVC then forwarded to the embassy. Do some research before starting. Visa journey has some great guides that you can use as resources

Welcome to the site and the journey

Start by reading these guides found here on VJ, under the Guides tab. Read also the i-129f instructions.

After doing this research come back with specific questions. Basically most answers are found there.
 
Good Luck

Welcome to VJ.
 
First off, start here with the guides for the K-1 visa and I-129F petition : http://www.visajourney.com/content/k1guide
 
You both need to fill out the required forms, sign and date(you the beneficiary can print, sign and scan him a copy, his needs to be all original wet signatures). Then once the packet is completed mail it to the Lockbox in Lewisville, Texas.
 
The passport shouldn't be any issue as long as you are a legal resident in Italy, you can process through that embassy. If not, then you would need to return and process through the Moroccan embassy, and it is probably a lot better/easier to go through the embassy in Italy I would think.
