YAY! You must be really excited. I have to say that the Chicago consulate was AMAZING! I went on St. Patrick's Day (for good luck!) and it took about seven minutes for them to approve my visa. I was also there about 20mins early and they let me right in.
I think as long as you have the needed documents (and I had that and MORE!) you'll be fine. The funny thing (well it kind of peeved me at the time) is that they didn't even look at everything they request people bring. I spent so much time getting everything together and they only really looked at a couple of things.
Oh, if you have pictures of you two, bring them! She spent the majority of her time looking through my scrapbook!
