What type of boxing gloves should I get?

Well someone gave me a small punching bag the other day, I think its around 30lbs. I was wondering what type of gloves I should get to hit on this thing. I have small hands and small wrists, should I get hand wraps too, or just gloves? I never was really into boxing, but I want to start getting into some boxing workouts. Also, I tried looking on sportsauthority and sportinggoods websites and not sure if there is specific gloves just for a punching bag. So what kind of gloves should I get and how many ounces? Thanks. Would these be ok for what I am looking for? a href="http://www.ringside.com/All/productinfo/EVPSTG" rel="nofollow"http://www.ringside.com/All/productinfo/…/a
