Neural Dream,
Don't know if this helps; but as to the Hellcat and Avenger, Barrett Tillman has great books on both.
Here is a link to his site. It has a good number of his books that might help you out with your questions. I have read some of them and enjoy them immensely.

Also, here is a link to a forum that is fantastic for historical research on Japanese aircraft.
