Your gear looks nice, a good amount of EH while maintaining Uncrush/Uncrit. In other words, a good progression set.
If I were you, I'd start putting together a threat set and a high avoidance set. Once you start getting the gear, it's all about flexability in gear. You don't always need that much Effective Health. It's actually more effective to have a comfortable amount of Effective Health and focus some of your stat points towards threat/avoidance.
Being able to maximize your stats on an encounter per enounter situation will make everything smoother.
I have an avoidance set i plan to use for lootreaver:
11.8k hp in that and 53.9% total parry/dodge/miss..
as for threat im a bit lacking on that stat (spell damage) having passed on t4 shoulders 3x has hurt me quite a bit and after the 3rd time that guild disbanded meh..(passed to healers who were using poor shoulders..)
And err bag space sux..healing gear, tanking items, pots..im seriously considering investing in a mana potion injector...just to free up 2 bag slots but first maybe upgrading to 18 slots T_T..
