I'm sure you'll get lots of good information in this thread, I've been out of the game too long to offer anything useful. One thing I can offer however is some terminology. If you have a a dialog with a recruiter and he's using the word "enlist" - stop the conversation right there!
If you want to fly in the military, you want to pursue a "commission". Pilots in the Air Force are commissioned officers, and are not enlisted.
Your on the right track to ask questions, and from your apparent knowledge on the subject - keep asking. Don't sign anything until you're fully informed and comfortable with committing the next 10 years to uniformed service.
