The main thing they're looking for at this point is any flying that you've done that required a commercial certificate because it counts towards your 1000 hours.
Call Kathy. She'll be able to clear everything up. I probably called her 10 times from just before the interview, to just before class with lots of annoying questions. She's very helpful.
