Do two more runs through BM to obtain revered with KoT and get Glyph of the Defender enchant for your head piece.
Complete the quest line for the Arcatraz key and get Sha'tari Vindicator's Waistguard to replace your belt.
Complete the quest line for Dabiri's Enigma to replace your Regal Protectorate.
I would also replace your Iron Band of the Unbreakable with your Violet Signet from Violet Eye Rep.
Unless your getting stuck on a boss, alot of this will be replaced early on in Kara anyways.
