Have you tried searching on the site airforcehistoryindex.org ?
It is an index of the Air Force Historical Research Agency holdings. For those reels that have been moved to CD, the cost is $30 per CD.
It includes some links to search tips and ordering information.
Searching is done something like this. For the 355th FG, which consisted of the 354th, 357th and 358th FS, you could search as follows:
Starting on this page:
http://airforcehistoryindex.org/search.php
Using search terms: Group/0355/Fighter and between say 01/01/1940 and 12/31/1945
http://airforcehistoryindex.org/sear...12%2F31%2F1945
Gives 32 "hits"
not all relevant. If you click on the blue number in the left hand column you get details of the item, in particular look at the Reel Number and IRISREF Number. Note that many items will have the same numbers so will/should appear on the same $30 CD (if available).
A 358th Squadron search example might be this, again not all items found are relevant:
http://airforcehistoryindex.org/sear...0&L=12/31/1945
You could do similar searches for the other squadrons.
Hope this gives you somewhere to start and some ideas on what is available.
