All you need equipment wise is a reliable pistol, three or more magazines, strong side holster, belt carriers for two magazines, and a "concealment garment." Eye and ear protection, of course.
You can and should practice the draw dryfire and then learn the draw from under concealment dryfire for safety's sake. Dryfire practice of use of cover is a good idea, too.
The Georgia new shooter's briefing is very helpful and easier to get your head around than the rule book.
