First I'd start with farming the 3 socket gem for the same belt you're wearing. Then I'd farm the Breastplace of Righteous Fury for the +5 Crit whereas yours is +3, and you don't need spell power. I'd farm the gem slot shoulders if you want to go for speed + Truth Bearer Shoulderguards, and the Ironblade Gauntlets for gems. Personally I'd dump the rings and go for the +12 crit from TW Classic dungeons. When BC TW comes out, I'd go for the +13 crit helm, and Shaarde of the Greater x2 for the +13 crit ea weapon. Though, I'm a crit build. The shoulders you got are great, and I do have them as well incase they nerf the speed boost from the SL gems.
