Talk to your supervisor at your squadron. When I was enlisted they told me there used to be something called bootstrap, I beleive. It's where they let you out of active duty, pay for your school, commision you and bring you back in. I was going to look into it but I got out and now I'm just doing AFROTC. I don't know if you have already but make sure you get good EPR's, do whatever you can to get alot of bullets. Also Airman of the quarter or year probably wouldnt hurt either :).    Stay out of trouble, its alot easier as you know to get into trouble in the military then civilian so keep your nose clean. Start off right with school, don't overload yourself and take it seriously.
