Your gear does need some work but you're on the right track. Of course you still have some upgrades from 5-mans, like Tears of the Vanquished (which is still an amazing mana trinket, much nicer than the SP one you're using, for raiding anyway), or the shield from H PoS. Aim for haste/mp5 itemization where possible, but of course when you're gearing up you don't necessarily get to choose the gear that comes to you. The level 200 libram from emblems of heroism is still superb for mana conservation when raiding, I would grab it when you get a chance.
Also, is that a spirit enchant on your legs? Bad boy! *rolls up newspaper* Get the stam one.
