Gear advice requested

I am requesting advice regarding gear selection for my Assassination Rogue. I know that 4.3 will boost melee DPS, but I am hoping that some friendly advice might help me out in the short term.

In addition to the gear I am wearing, I have the following gear available:

• Breastplate of the Incendiary Soul : http://www.wowhead.com/item=71314
• Riplimb's Lost Collar : http://www.wowhead.com/item=71640
• Dark Phoenix Tunic : http://www.wowhead.com/item=71045
• Dark Phoenix Gloves : http://www.wowhead.com/item=71046
• Dark Phoeix Legguards : http://www.wowhead.com/item=71048
• Clutches of Evil : http://www.wowhead.com/item=69942 (I have the recipe, have not made them yet)

I have the T11 4pc bonus, and only 3 t12 pieces. Majordomo is a few boss fights away, and I have been trying every week to get the t11 head piece from Nefarion.

check out my "STOP! ..... try here first!" thread i made the other day, it has tons of links to great resources that basically take all the guessing out of making the most of your character.

I hear good things from Rogue friends about http://shadowcraft.mmo-mumble.com/
