I have 315 arena points from losing 10 games in the 5v5 arena and hope to have another 300 or so points in a week. I will slowly save my points to get some good gear.
I now also have 12,000 honor and saw that I can start to buy S2 gear from the honor vendor's.

The shield is about 10k and the S2 weapon is 25k. Given I will not likely ever get 1600 or even about 1500 in arena, what gear should I buy from Honor, what gear should I buy from welfare arena points and what gear should I buy from Honor badges?

For the Elem Shammys: I want PVP gear. I think that can also be used relatively easily in 5m heroic instances (all I need there is spell damage and crit).

For the Pally, I want gear that would be good for herioc tanking. That shield and S2 weapon looks good on that front. The spell damage is better than I can get from Conntiumum blade

Please help me in determining what gear should be purchased with honor, which should be purchased with arena points and which with heroic badges.
