Equiping the "best" gear in every slot should get you way above 40k. Looking at your armory one thing I see immediately is that you seem to go for all the socket bonuses. You even have some pure strength gems in there. Change all your gems to pure stam in rawr and look at the difference from just that (without saying you should do that for real on your char in every single socket).
One must remember that even if you didnt put in a single dodge gem you would still have plenty of dodge from gear. The stats you get from gems is very small compared to the stats you get from gear and talents.
