Hey man, how;s it going? I did 8 years of AD as an Intel Analyst and did exactly what you're trying to do right now.
As far as the process of getting out, you have a favorable DOS that lines up well with most school's start date for the fall semester. If you don't have enough leave to get out and go full time at the beginning of the semester, look into the Separations AFI. There is a section in there that says you can separate up to 90 days early from your current DOS to go to school.
As far as getting into AFROTC, there's really nothing to it. As long as you have a GPA above 2.5 and no crazy medical issues, you can just sign up for the class and LLAB and you're in. I would start getting to know the cadre at whatever det you plan on attending. That helped me a ton with coming into a Detachment as essentially a 250 (you're more than likely get your 100 year waived because of your enlisted experience). Understand that each detachment is different; when I got out, all I kept hearing was that I was going to be frustrated with being told what to do and what the AF is like by 19 and 20 y/o. But in my det, they were extremely cool with me, and worked with me based on what I already knew. Like I said, it varies det to det. Be prepared to be busy, especially if your going for EE or some other engineering degree. ROTC will take up the least amount of space on your credit count, but you'll be spending almost all on your time on ROTC related business.
As far as what you can be doing now. Like I said before, get to know the cadre at whatever detachment you plan on going to. Also, apply and get accepted into the University now and start knocking out your classes. You have to maintain the minimum full -time credit count (12 c/h), but if you can get it as low as you can, that frees up more time to focus on Field Training Prep. If you REALLY wanted to get a head start on things, you could start reading the Field Training Manual. That is basically everything you will be responsible for knowing down at Maxwell; focus on warrior knowledge and verbiage.
The GI Bill is good, especially the Post 9/11 one...I will say it won't be enough to really live off of. Basically you're only making $1,150/month, so you'll need to at least get a part-time job if you have no other income.
Last little bit...don't be *that* guy who relies solely on his enlisted experience and thinks he is above everyone because you've been in. If you go in like that, I promise you will be ranked at the very bottom of the bottom third of your class. Be humble, share your experiences but don't be condescending about it. When a POC gets in your grill (and they will), try to be as objective as possible. Feel free to PM me; we can exchange contact info and I can help you out more if you need, especially with the transition.
