Filling out your CCS/ASRA license application ahead of time will help. You can come in on Saturday morning early and take care of that and sign up for races. (The clerks can give you all the forms you'll need when you're getting your weekend pass and/or during the Team Hammer registration - when you're at the window.)
BTW, if you've been licensed by any other race organization in 2009, the school isn't a requirement for a 2010 license.
