Have you taken the class yet? That is the first thing to do before anything else.
Also, if you haven't filed your application yet, there is some excellent info in the Gun Laws section about how to write the letter for the application. I suggest you read it carefully. It really is helpful information but together in large part by competent attorneys who frequent this board.
You might check Ritchie's gun shop (there is a thread here in the Gun Shop forum) in Westport IIRC. Nice guy, nice shop and can probably point you to places to go for the required training as well.
