When it comes to gear I look for the highest armor with the highest str, everything after that is just an addition. Weapon dps is important so even if you're not using a +67 str hammer look for something with a higher weapon dps.
Mastery is to run grace spec and get the tactic for the toughness debuff tactic, its the only thing that seperates us from DoK's for right now and it makes a massive difference in your dps and survivability.
Hope this helped
