First of all, the gear is a mix of tank and DPS, such as the Felsteel stuff, which isn't too suited for PvP. You'll have nice mitigation, but not enough AP or crit etc.
Second of all, the spec. Any form of 61 in one tree spec for warriors is terrible. Also, arms is far more suited to pvp. Give a 33/25/3 spec a try and you'll probably do a little better.
Thirdly... Aye i'm done for now :P
