Grab that skinning knife and get those Medium Armor Kit. It might just be 24 armour but if you want to have BiS gear, then you'll need to get those (once you're done with leatherworking, use Alchemy and Herbalism again).
You've got quite a high number of HK's yet you're still using the insignia from Ashenvale. By now, you should have gotten enough honour to be using Inherited Insignia of the Alliance (it's got 6 resilience, unlike the one you're currently using). Try to get that.
Use Foreman's Leggings. Those leather pants should only be used as a substitute for when you're farming the mail legs.
I'm judging by your Stamina Cloak/Belt that you've got your FC gear on. If that's the case, then use Thick Bronze Necklace as your neck and Silver-Linked Footguards for boots, to get that extra Stamina. But if you're using Prot spec for DPS'ing, then the current necklace and boots are fine, and instead you should be using the "of the Soldier" Cloak/Belt.
