What gear to buy with EOF?

Here is my character link: http://armory.warmane.com/character/...ecrown/profile

I currently have no t10 set pieces. I have the EOF trinket. I was wondering which piece should I buy? I was thinking of not buying legs/gloves because they drop from VOA and start by buying chest piece. I have 103 EOF atm.

Also, I currently use DW Frost as main dps spec (although if there is another FDK in the raid I will switch to unholy) Is this wise? or should I stick to DW frost at my gear level?

Thank you. Sorry for poor english

Save up 155 and get shoulders+helm or chest. Refund EOF trinket if you still can.
