I personally don't see anything very wrong at all. It does depend on what content you are aiming for currently. If it's ToC 10 man you should be fine.
Think about changing the enchants on Gloves, Weapon and Shoulder. Also consider using the trinket from the new 5 man with the stamina and armor on proc.
Bladeward is a very nice enchant for pally tanks... not so sure for warriors... i went for Blood Draining and found it very good to have on our first few tries <read 15 wipes> in heroic 10 man ToC.
Shoulder enchant i use the PVP 30 stam one for 10k honor, right or wrong i dunno... but 300 hp + is always nice
