Your list is good, and should be, for most officers, complete. I would ask you one question though...what is your living situation? Do you rent? Do you own? I would add a copy of a lease or a deed/mortgage. If you live with friends, or with family, then include an affidavit from them describing your agreement, and how the two of you contribute to the household.
This is not a requirement - but might go a long way to add to your "co-habititation" paperwork.
Best of luck to you both!
