If just started martial arts is it normal for my wrists to hurt or is my punching form off? Also what's a good brand of glove?

It depends on what kind of pain you're feeling. Is it just the kind of exertional hurt that you get when you've started working out a muscle you haven't before? Or do you get this sharp, stabbing pain whenever you flex your wrists back or forward? Try wrist wraps next time to protect them.
Also the good brands of gloves may depend on what kind of martial art you're doing. I mainly box so I use Twins. Everlast seems okay.
