For a start, good luck at your regional!
Off the top of my head, I don't think that there are anymore awards that you can submit for, but someone please correct me if I'm wrong. I'm not sure if you guys can submit for the Media and Technological Innovation award, but I would presume so. Check out
http://frc-manual.usfirst.org/viewItem/9 for the award criteria.
There are a few awards at the regional that need preparation, even though it is judged at the regional. The Imagery Award is a good example.
