whoever told you to get your parry rating up doesn't know what they're talking about
Your stuff looks pretty good! Be ready to be flexible though--even upgrading one piece of gear can cause you to have to swap gems / enchants around sometimes.
One awesome post on Veneretio's blog (you can read it here:
Should I Gear, Gem or Enchant for Defense? - Warriors - TankingTips.com) has really helped me with seeing the comparison of the best ways to reach 540 defense while maintaining as high a health pool as possible. I'd urge you to take a look at his post.
Based on his math, I have a few suggestions for you:
1) get the 22 defense enchant on your chestpiece.
2) get the 16 defense enchant on your cloak
3) replace the two 16 defense gems in your chestpiece with 24 stam gems.
These changes will increase your stamina by 38, while raising your defense rating by 6!
