Let me chime in and explain raw. There are 2 kinds of raw, classic raw and raw.
Classic Raw is allows for knee wraps, wrist wraps, and a belt
Raw allows knee sleeves, wrist wraps, and a belt.
If you're looking for equipment than you would need to decide which type of raw you would like be under and than pick up the few items. You'll also want to get a good pair of shoes. I personally think Spud Inc Suspension straps are worth their weight in gold so I'd also recommend you pick up a pair of those as well. In case you need to dump the bar and don't want to get folded like a lawn chair.
You'll have to see what federation you want to compete in b/c that will dictate the length of the wrist wraps and also knee wraps (if you decide you want to go that route).
This can turn into a very big discussion so let talk about this more so we can get you on the right track.
