WoW 4 Elemental Shamans at 85, gear advice needed.

[Lasivian]

Ok, background.

I have 4 elemental shamans that just hit 85.

I've been doing alot of PvP and my JP/Honor are both capped at 4000. As an example I can handle the trash in Vortex Pinnacle Heroic with a good tank, but can't take the first boss.

I made myself the "Vicious Charscale" set x4. I've also bought [Bracers of the Spectral Wolf]x4 and [Sabatons of the Graceful Spirit]x4 but have not bound them yet.

I'm debating how to spend my points, with the desire to do heroics and raids eventually. IE. Should I invest in the best PvP I can get until I can hammer my way through heroics with overwhelming DPS?

Any info would be helpful. Thanks.
