Current Gear: The World of Warcraft Armory

The problem is I am not sure what DPS is good for me for 10/25 man Naxx with the gear I have right now. The only record I have saved is 10 man Loathweb I was doing 3.6k DPS. Any pointers and/or recommendations are welcome and appreciated. since Armory might not have updated fully, I had a +27str gem in the helmet. I know that I'm still missing some enchants, but with what I have right now, What are the expected DPS?

I follow the rotation: WW>BT>Slam and over 50 rage HS spam. I would ONLY do Slam when both WW and BT are down.
