Just Fly,
You simply need to take the FAA's Military Competency written test to earn your Commercial Certificate. If you are an instructor you can also take a Military Competency CFI written test and earn your Instructor Certificate. These tests are both very easy to pass with the help of some study aids. I recommend Sheppard Air. They have a great study program and their website will explain exactly what you need to do to get your tickets all the way up through ATP. Many base Education Centers offer the FAA written testing for free. [URL="http://www.sheppardair.com"]
Very few of the CTP courses have been approved by the FAA. I attended ALPAs Pilot Shortage Conference today and they report that the FAA has over 60 applications for companies awaiting the FAAs endorsement. So I don't think you will see many more programs added any time soon. AEROSIM offers an ATP/CTP course and an ATP particle prep course. The ATP/CTP course will run you about $5000 and the practical prep course will add an additional $3800. However their website does not advertise their practical prep course. You'll need to call or email to get the info.
Just curious, why are you leaving the AF? Do you expect to go directly to the Majors or looking for a Regional job? I also heard today that there is a shortage of Helo pilots across the country. Your skills will be very valuable both in and out of the Air Force.
