I would certainly see a US attorney who specializes in pre-nups and have that in place prior to the marriage taking place after he arrives on the K1.

What documents will I need to provide to show "proof of a relationship" aside from affidavits from 2-3 people re: being in a married relationship, pictures from the marriage celebration, and the marriage certificate. Will i also have to provide documentation to show our conversations over the past year such as yahoo, skype, phone and text records? I am also 18 years older, what obstacles will we face in the process?
There is never such thing as having too much documentation.
So put together a binder loaded with all of this evidence in chronological order. It is what would best serve your sposue to prove that it is good faith.
