well, fwiw...there are some things to consider with your current spec and gemming
1.) you shouldn't be gemming for haste until you're at 1200ish damage and when you do, you need to toss more than a gem here and there at it
2.) you spent points in elemental precision which implies you plan on hitting a boss, yet the talents in the frost tree aren't PvE oriented particularly; i would look at lowering your FB time and spending points in the crit/dmg talents before the right hand of the tree...if raiding is the intent; on the other hand, your hit rating is too low to cast anything other than from the arcane school, so perhaps i'm mistaken
3.) gear wise, you're really at a point where 10/48/3 should give you better results
4.) i'm assuming if you're going this route you're using ABx3 FBx3?
5.) hope you have a shadow priest *and* a shammy in your group!
