Help me tweak my specFollow

I was formerly a raid tank, but I got tired of staring at bear butt. So i dual spec'd to resto since I had picked up quite a bit of gear no one wanted. I then grew tired of raiding completely, so I shifted my focus to pvp. I started with BGs, and picked up some gear in VoA. Im working as best as I can to get my resil up, in a week ive gone from 95 resil to 490.

With all that said, I havent changed my spec. Im still in a raid heal spec and need to swap some points. I just started arenas on thursday, so my expierience is very linited. Also this is my first pvp healing toon. I was thinking about picking up Natural Perfection and Improved Barkskin, Im just not sure where to pull the points from. I have 1 point in Empowered Touch, Im not sure why I put a point there. So I need to pull 4 more points from somewhere.

So to sum it all up, are Natural Perfection and Improved Barkskin worth the points? Where should I get the other points from? If I pull points from other talents would I still be able to heal raids and heroics effectively?

Thanks in advance for any advise.

dont forget to grab the glyph of barkskin too. -25% chance to be crit when barkskin is up = win. comboed with imp. barkskin, you became *VERY* hard to kill.
