US Immigration from Morocco

My fianc is insisting that I re-scan all of the evidence I sent with the application because someone told him he needs it in color. I already sent color scans with the application. It's my understanding that they will have this already for his interview and that he should bring different pictures to his interview. Is he correct? Do I need to re-scan all of the call logs, passport stamps, photos, receipts, etc. again so that he has a color copy?

I'll start off by stating I'm completely lost right now.

A few weeks ago I emailed the Consulate in Casablanca with a question. I was sent Login information for the CGI Customer Portal (I don't know what this is). Then I received another email asking for a scanned copy of my approval letter from USCIS. Today I logged in to see if my question was answered and there is a fee there. I'm so lost right now. What does this mean? When should I pay this?
