And enchant your gear. You've a few, but you really should enchant every piece possible. Aethien's Preraid Gear List, stickied at the top of the forum, also gives suggested enchantments.
Replace your one green trinket with something blue. The armory offers a 'suggested upgrade' feature. You can use that. Alternately pick something out of Aethien's list. Bladefist's Breath is readily available from a quest in Hellfire for instance. Bloodlust Brooch is better but requires turning in badges. I imagine you've got a stock of those given your gear.
Put a meta gem in that helm. There's only one good one for hunters -
Relentless Earthstorm Diamond Alternately go get the BeastLord Helm or Warpstalker Helm and gem that one. The Desolation Helm, what you're currently wearing, is really Shammy gear.
Oops, yeah Kusa. I missed that detail.
