Congrats.

Yeah, if it's not going well it's always my fault, yet my team mates have stood next to me on their horse watching me get slaughtered then blaming me for multiboxing in the BG, LOL.

Check out the pvp blues from the various rep vendors. Looks like you can get at least two pieces right away (honored Thrallmar and Cenarion), they'll be good for boosting your resilience right away in BG's. A few farming runs in Mechanar for your Totem of the Void would get you a third piece from Sha'tar (kicksome has a great totem farming tutorial video linked on this site).

Here's the pvp blues set:

You're gear is very close to what I had when I dinged 70 as well. Talkbuk weapon, chestpiece, bracer, lol. Brings back memories.

Rogues...I drop 5 magmas immediately, that helps a lot.
