Getting back into mage PvP - Need a few questions answered.

[Furiouz]

Hello fellow PvP'ers, I have just recently started PvP'ing on my mage again and there's a few things I wanna have sorted out before I start gearing it. First off I wanna start by saying that I've played mage a whole lot over the years but mostly in PvE and very little PvP, the PvP I did was mostly in my PvE gear and wasn't something you would see often, so the questions I have doesn't involve the way of playing the mage but rather which stats I should go for, whether or not my spec is okay and last but not least caps (Hit cap, spell pene cap etc.)

So here is my spec: Frost 2/8/31

Add-ons I use: (Please notify me if there's something vital which I'm missing)
ForteXorcist
LUI V3
Decursive

As of this moment I am not quite sure which stats to gem, enchant and re-forge to? If anyone would be kind enough to post a PvP Frost mage Stat priority list I would be very happy

Best Regards, Furiouz.
