Help on Upping DPS

[slush20]

Hello Friends,

I've been playing TV Frost mage for about 1.5 months or so and I feel like I can do more but am not able to. I currently have a 200k disparity between my sim and my actual. (1 mil simmed, doing 800k or so). Any advice would be appriciated. Also, tips on the heroic KJ fight would be appricated. (over 50 pulls and I cant seem to get a good parse on it)
