Gems for warriors are:
Red = Parry/Mastery
Yellow = Mastery
Blue = Mastery/Stamina
Meta (helm) is Sta/Armor.
You'll also want to reforge.
If it doesn't have mastery, reforge into mastery (even if it means reforging dodge/parry).
If it has mastery and something other than dodge/parry, reforge the something other into dodge/parry.
If you can reforge haste* first, then hit, then expertise, then dodge/parry, then mastery
*Haste is only thrown in there becasue when gearing, something with a ton of mastery and haste, though technically a DPS item, might be an upgrade and the haste could become dodge/parry.
You'll want to try to keep parry roughly 2.5% higher than dodge through reforging.
You're missing a few enchantments too - blocking on your sheild, a mastery enchant over stamina on your boots, the higher stamina enchant on your chest, the enchants on your wrists, legs and cloaks and for you rings - are you wiating until you make them for leveling enchanting?
How are you doing on threat? There's a lot of... situational choices in your talent points that may better suited for threat.
