Yeah - what Klausi said - I do similar damage as well on the dummy, with much the same gear. Only difference is that you are speeced into B&T and have left out Executioner. I would have used 2 point you put in incite and put them in executioner. The extra attackspeed does mean quite a bit of extra rage/more damage during exe-phase.
Besides that practise, practise, practise and it will come. I have been exactly where you are a month back when I shiftet to arms from fury.
Btw I used Landsoulds POV-video on madness heroic and got a few tricks from that. Im guessing you can do the same and easily pull 50+k on Madness normal like the other warrior in your guild ;-)
