What DPS do you pull? I didn't look at your talent tree, there may be something there, but the big thing I noticed was your gear, lack of enchants and gems.
I don't know if you're wearing a mixture of PVP gear for a specific reason, but if you aren't - replace it. Spend your Frosties on the 251 gear in Dal (just like your chest), or at least spent Triumph emblems on the 232 set, like your gloves. Replace your back, bracers, belt, legs, shoes, ring, and PVP trinket.
As far as upgrades for those go, from memory you can get a 264 back with Frosties (if you have them), when you fix your gear up a little there are plenty of similar lvl upgrades you can get in ICC.. but there is stuff that drops in ToC that would be useful, like bracers and a belt... er, I think.. and 232 shoes drop in HoR H.
Get rid of all of your weird gemming... resilience does nothing for you unless you're in PVP, no point in gemming haste currently, and stamina does nothing but increase your health. You should get the haste/hit you need from your gear when you fix that up.. just gem agility! 20 agility gives you your attack power and crit. Don't gem attack power.
Kind of hard to give you more advice, I don't know if you're wanting to raid, or run heroics, or PvP.. or what... good luck!
