New fury warrior

Hello, I started playing a few weeks ago and decided to play fury warrior. This is my character - http://armory.warmane.com/character/...mourne/profile
I have a few questions.
What weapons should I use and where can I get them?
What gear should I use and where can I get it?
Is there anything good I can buy in AH?
Should I always stay in Berserker Stance?
And should I use Battle Shout or Commanding Shout?
Thanks for your help!

While doing RDF HC for some gear, and daily EoF, and additional EoT's:
FoS PoS ToC normals
FoS PoS ToC heroics
ToC 10/25
VoA 10's, 25's too if you can get in.
Weekly raid quests.

BoE items you could check: Wodin's Lucky Necklace, Ring of Rotting Sinew.
Almost always on berserker stance.
BS or CS, in short: If there's no paladin buffing Might, use Battle Shout. Otherwise Commanding shout.
