Easiest way to get that GS up is to make sure you have all the iL245 items from triumph badges so rings, helm, shoulder, (class item), one of the trinkets etc. The rest is T9. Run heroic frozen halls every day to fill out the rest with 231? gear like weapons, rings, trinkets, neck etc etc. There are a few other iL245 crafted items out there as well if you have mad cash to spend like bracers, chest and stuff. If you cant afford them, you can get the mats and prolly have someone make them for you. As far as T10 gear and crafted items go... Take a look at what drops in the first wing of ICC and dont buy any of that with your frost badges, maybe look at what drops in wing 2 and rule out that gear as well because you might get it on a pug.
