Some gear has hit rating, go look on wowhead for deadly gladiator and check the leather options. I would suggest putting together an arena team so you can lose 10 games a week and get some arena points. That way when you go to buy stuff from the pvp vendors you can get stuff cheaper (there's a pvp vendor under dalaran that sells deadly for honor + arena points). Much cheaper than buy from honor alone (which I did, god did I farm AV forever.)
Also do WG when its up, that gear all has hit on it.
