If you aren't using Rhinolicious Wormsteak, that's a quick and cheap way to increase your expertise to the soft cap (you have 22 at the moment, and the soft cap is 26 -- the food buff gives you 40 expertise rating, which equals about 4 expertise skill)
Unless you're rage starved (which you shouldn't be on fights like patch) you'll want to use heroic strike every single GCD. A good way to do this is to bind heroic strike to your mouse wheel and then just roll your mousewheel constantly the whole fight (if you bind it to mouse wheel up and mouse wheel down you don't even have to move the wheel too much). I think the parse you linked had 33 "white damage" swings that could be translated into Heroic Strikes!
