Oh boy, there is alot you need to do.  I can only speak from a 7-day opt or VSP kind of front, but you NEED to tell the active duty AF you are leaving.  Vmpf is a good way of doing it, be-it a 7 day option or separation thing, it needs to be done.  You also need 2 recruiters, one ISR (which you have) and a ANG/ARC recruiter.  I realize what the ISR is telling you, won't hurt to fill out an application or 4 on vMPF telling AD to F off.  The Total Force Center at Randolph is actually pretty good, call their 1-800 number and ask them, you'd be surprised.
