Hi Baronpete,
I'm in the same boat, but just a little ahead in the process. For me personally I was lucky enough to have two individuals give me detailed info on the process, but there is a lot of info online also... baseops.com has a forum like this where you can find out allll the info you want.
you'll want to go find an accessions officer, he's like the equivalent of a recruiter except he does officers instead of enlisted. he will give you a CRAPLOAD of paperwork to complete which seriously takes hours and hours so you want to get started on that! he can also set you up for a flight physical which I heard the units like to see when you apply to them because they know they're not hiring someone who will just end up DQing.
also, take the AFOQT and TBAS (which will give you a PCSM score) as soon as you can, and see how you do. these will better determine your chances and you will need them as part of your package. in fact, I took these even before I went to see the accessions officer so that he knew I was serious. Barnes and noble sells an ARCO study guide for the AFOQT. you can take these tests only twice, so you might want to study that ARCO book, but if you are reasonably intelligent there is no reason you shouldn't do well. I took mine at the local ROTC detachment.
as far as vision goes I have similar vision as you, with astigmatism. I heard and read a lot of conflicting info about vision, even from recruiters and base commanders alike (you'd think they'd know better) but the best things is to find the rule book and see what it says. I had someone at the ROTC detachment (when I dropped in there to take the test) look it up in one of their very thick books and it said 20/70 correctable to 20/20.
I think the hardest part is trying to contact the individual units and hustling yourself for an interview. That's the part where I'm stuck. My accessions officer gave me a list of units but half the phone numbers weren't even current.
