Neck - Regem that for +30 stam
Shoulders - this appears to be your current highest +stam red socket bonus, put your red/stam gem here. Also re enchant with +30stam/15 resil PvP shoulder enchant (10k honor)
Cloak - re-enchant with 225 armor
Get Blood Draining on your weapon.
Trinkets - replace the corpse tongue coin. Glyph of Indominability would be an excellent choice.
Boots - Enchant with Tuskarr's Vitality instead, the runspeed is amazing
Belt - get a different belt, an easy choice would be http://www.wowhead.com/?spell=63191 and it is crafted so you can get it easily. Also, if you get this belt then you can put the red/stam gem in the belt for a +9 stam socket bonus and leave the 30 stam gem in your shoulders and still keeping your meta activated.
Gloves - get 240 armor to gloves enchant (18stam would be acceptible too)
Your spec is very wacky, I suggest taking a look at the spec section of my guide (link in sig).
