More upgrades before MTing Naxx 10/25?

[Blitzed]

Hey guys! It's Blitzed, I used to play as Luzbelle/Lyfe with Temig on Khadgar. I played for a little while with a lot of you on AoC in Eventide. Well, for this xpac I decided to switch to my warrior. I hit 80 on the 14th and have been running heroics like CRAZY (yes i made 95 badges in 4 days). Well, I'm all set up, got my expertise OVER the 5.5% cap, got OVER my 540 Def and hit my 22k armor. I'm just wondering, am I ready to MT naxx gearwise? Do me a favor and let me know what I need to get, as of right now I'm looking at Essence of Gossamer for the 2nd trinket and Arcane Shielded Helm for a hat. Anything else I need? Thanks for taking a look.

BTW I copied my spec from people i saw, any differences i should make for Naxx tanking Vs. Sarth/Maly tanking?
thanks
