Anything I should with my gear for better DPS?

Thanks in advance.
those are some strange gems you have.

prismatic: brilliant inferno ruby
blue: veiled demonseye
yellow: artful ember topaz

but your chest, just put 2 brilliant inferno ruby. reason is mathematical.

reforge.
hit to 1742
haste to 1768
after that, everything else mastery.
crit is what you reforge out of first.
you can use programs like rawr to optimise for you.
Replace the Bottled Wishes with simply anything else. It is only useful for Heroic Spine. Any other trinket from FL or DS would be better for you.

Use the Glyph of Arcane Power.

Regem so that you are only using Brilliant red (int), artful orange (int/mastery), and veiled purple (int/hit) gems. Get rid of the jagged green, nightmare tear, and the level 80 gems. The potent orange is okay... but artful is better.

Reforge to adjust your hit to 17%... anything over that is wasted.

Reforge out of haste and into mastery (or crit). You want aim to get your haste rating down to 1768 (1268 once you get t13). This haste value is the amount of haste that will put your AB cast down to 1 second during hero/timewarp in a raid.
