Buddy of mine just finished training there. He was a low time guy and not a CFI. It's easy enough to apply so go ahead!
As far as interview books I've got a small stack I'm avoiding reading. I can't seem to get anything really practical out of them. Lots of people will teach you if you've got the money. AIR Inc, Emerald Coast, lots of others, etc. Emerald Coast gets rave reviews. If you're going to an AIR inc job fair consider adding their interview seminar. Its relatively cheap if you're going to be there anyway.
