Level 52 warrior - gearing advice going forward?

[Soothsayer]

I hit level 52 the other day (which was one of my more significant goals, since evasive discipline is absurdly good), so now I'm wondering what sort of equipment upgrades I should be on the lookout for heading into Karnor / raids / etc. Ideally, I'm looking for upgrades that don't cost a fortune. As much as I'd love to have a runebranded girdle... [You must be logged in to view images. Log in or Register.] well, let's just say earning money as a warrior is relatively difficult.

Here's my current setup. I'm at 980 displayed AC unbuffed with 2520 HP.

Head: Custom Champion's Helm
Face: Grotesque Alloy Mask
Ears: Cougar Claw Earrings
Vambraces: Champion's Vambraces
Chest: Champion's Breastplate
Legs: Champion's Greaves
Boots: Crystal Chitin Boots
Wrists: Ice Forged Shackles, Bracer of Scavenging
Belt: Mithril Plated Girth
Hands: SCHW
Neck: Spider Fur Collar
Shoulders: Barbed Dragonscale Pauldrons
Back: Cloak of the Maelstrom

My neck and bracer items are fairly cheap, but I'm struggling to find replacements. The collar has a fantastic 10 AC, and the belt adds a nice chunk of stats and decent AC.

Edit: Weapons are Frostbringer MH and Sarnak Warhammer OH.
