Scrap the purple gem from your boots, gem only for agi (delicate) (red), agi/haste (deft) or agi/mastery (adept) (orange) or agi/hit (glinting) (purple). Set bonuses are only worth getting if they net you +20 agility or if they net you any agility and you're not hit capped (blue slots). Change the bracer enchant to 50 agi, glove enchant to mastery. shadowcraft.mmo-mumble.com/ <- use that for reforging after going through what I said, can't run it for you since I'm at work. The stats which assassination is after are Agi > Yellow hit > Spell hit > Mastery > Haste > Expertise > Crit > White hit.
Assassination benefits from mastery so you can mostly ignore expertise, don't reforge away hit unless you're hit capped, and fix your spec if you're going to be using assassination for raiding purposes
http://www.wowhead.com/talent#fcIf0sRdoGo0bZbhc:Vqzor <- basic raiding spec for assa, the Vendetta glyph isn't better than Rupture glyph. Also, with that spec you'll need 1332 hit rating to be spell hit capped.

You got the boots gemmed but missed the enchant?
Haven't played combat in a while but surely you prefer stacking haste over spell hit cap these days? At least from what I've read on EJ.

Nothing bad to say other than that really, use shadowcraft.mmo-mumble.com/ to see what's best for you.
