Need some advice relearning my Warrior (PvP)...Follow

Its been a while...

Retired my warrior a few weeks after TBC hit, pulled him out of the mothballs a month ago and managed to get him to 70, 2/5 Merciless and Stormherald. Currently he's specced 33/25/3.

ATM I tend to Charge > MS > Autoswing > Slam (If stationary) > MS > Autoswing > WW .....I Overpower when applicable, and even Disarm other 2-handers early in the exchange.

* In the BG's, whats the general attack routine on a moving target? (i.e. Slam is not an option)

* I commonly hear that we have an advantage vs Rogues, yet im getting shredded by them (Prob due to poor gear), how would one handle a rogue?

* Mages flatout CC/Own me, I cannot get close to seal the deal, is this common?

* Since im going for the Stormherald/Mace Stun spec, would a Brutal Earthstorm Diamond stack its proc on that as well?

Thanks for the replies, I know my Q's sound naive, but im trying not to assume anything about the warrior class since its been so long since ive used mine.

/cheers!
