Hit rating talents stack?Follow

Finally decided to clean up my arcane build. Was going to wait for 3.1 but I figure its only like 15g for me to respec and I might do alot of raiding till then.

Here is what I had in mind:

My main question is the 2 hitrating talents. Do those stack? Because if they do I could really cut down on alot of my hit rating and replace with spellpower. I have been doing more raiding and less pvp so I figure I can get rid of a handful of talents such as the extra armor based on my INT.

Also should I skip over the spirit talent? Seems like with the HUGE nerf to spirit with 3.1 it might not be worth it?

This is my current build:
