You are probably too late for the September 13th deadline, but it would not hurt to try. Get over there and make contact with folks in ops, they will be glad to take time out of their day to show you around, because Herc people are Herc people regardless of branch of service. They are probably interviewing for spots in FY11, which means they probably would not consider you as an outsider (albeit with prior military flight time) off the street without having your degree complete. If you could get a package in, and get an interview, they would definitely know your face and story for FY12.
The pressing thing for you right now aside from making contact, is to get the AFOQT accomplished. Get the ARCO test preps, unless someone else on here has a better recommendation, to get an idea of what is on there. If you naturally use good grammer and have decent reading comprehension and are reasonable at basic geometry, and algebra, you should have no troubles getting a pilot qualifying score. Your flight mech background and reading NATOPS manuals should serve you well when it comes time to the electrical diagram portion. Remember, you can only take it twice, unless there are very extenuating circumstances, so don't rush into it before you are ready. You will probably have to hunt around to find a way to take it, but the good news is there are plenty of AFROTC detachments at all the universities near you and they probably have one scheduled pretty soon with the start of fall semester--Call them to find out when---usually on a Saturday morning, so don't go drinking the night before.
