To tide you over until the dawnbreaker sabatons (or whatever the tank boots from jaraxxus 25 on alliance are called) you could get the
Spiked Deathdealers - Item - World of Warcraft built. Otherwise, given that you are stacking stamina in every slot, why did you take a dodge/stamina gem in the neck juwellery, given that it only has a 4 dodge rating socket bonus? I would have used a pure stamina gem (in fact I do).
as for talent choices; you have taken 2/2 SA and 5/5 divinity. I have run with 1/2 SA since it became a talent in the current form and only have trouble with vezax hardmode (although the extra mana from 2/2 probably wouldnt cut it anyway). 5/5 divinity is a less optimal choice, while 5% more healing taken sound useful, it will only really apply to hots, as direct heals tend to be 40-80% overheal. This means that out of the 5% extra healing you are only profiting from perhaps 2%, the rest is overheal and, as such, is wasted.
these 6 talent points could, however, be spent elsewhere in a more useful fashion:
http://talent.mmo-champion.com/?pala...Y6X1gV1,,10676 is how I have spent my talents for tanking.
Everything except northrend beasts is humanoid, UD, demon or elemental (and I think gormok and the yeti are humanoid), so you are skilling 6% more damage (about 14% more threat according to my napkin maths), 15% run speed and a passive demo shout as a tradeoff for overheal and too much mana for you to use.
The three points in reckoning are simply a filler, they can be placed in Imp. HoJ if you like the shorter CD interrupt.
