PvP gear is (almost?) always at Endgame-only, which in this case would be Level 85.
You would be better served to go out and quest in Twilight Highlands until you ding 85 and then get ahold of the Vicious set -- there's one for melee, and one for caster/holy. I will warn you ahead of time, the gear is a bit pricey and expensive unless you're a blacksmith.
If you're a blacksmith, all you need to make your own set is ~80 Volatile Fire and ~80 Elementium Bars (don't forget, each recipe takes either 10 elementium bars, or 1 pyrium bar to purchase if you didn't buy them already!). The Fires is easy as cake to get if you've got an herbalist/alchemist that can herb for life and transmute it to fire.
Or, you could enter PvP with quested junk and die horribly, repeatedly and/or get kicked out of BGs for weighing them down...
