What to stack.

[:1]Hey everyone, just got my druid to 85 and have full blue pvp gear.

just wondering what i should socket for/reforge for.
i know int is my top stat but should i focus on mastery haste or spirit?
I can only give advice for healing, and even that isn't perfect. Haste is good, more ticks on your HoTs and pop of Nourish faster, always nice. Spirit has become much bigger since Cata came out. Although Druids don't have a Spirit talent like they did in LK, Blizzard made healing challenging by making OOMing possible (gasp). Mastery is great for Restro Druids, since 70% theres an HoT of some kind on a player, so that bonus helps.
My personal recommendation is start adding on Haste if you're doing PvP healing. Your HoTs will tick more, so you can focus on the rest of the group during a fight. Mastery would be nice, since if you Wild Growth you can hit someone with Regrowth for a bigger bang. I haven't found spirit that helpful in PvP, but when I PvP heal, there's ALWAYS a rouge looking for me.
For Resto
Int>Spirit>Haste>Mastery=Crit
Follow that, for Boomkin, use spirit for your hit rating till your capped, then same thing but you dont need anymore Spirit....also Haste and crit are better than mastery for boomkin.
You said you had pvp gear but didn't specify if you wanted advice for pvp or pve.

If pvp, you may want to think about int/stam gems. I am fairly comfortable at around 2800 resilience. I have around 112k stamina unbuffed.

If boomkins were in a better survivability state, I'd be gemming to hit harder with damage spells but I really like to live.
