Go take another class, but not a "CCW" class. Instead, sign up for a two-day handgun class from a professional firearms instructor, someone who makes his living teaching firearms. You'll be amazed at how much more value you get out of such a class.
Or, if that's not in the budget, at least pick up two books:
1)
In the Gravest Extreme by Massad Ayoob
2) The appropriate state gun laws guide from
http://www.gunlaws.com/books.htm
Oh, wait, make that three. Buy my book too...
Hope it helps.
