The http://www.wowhead.com/item=51010 would be a good choice for you, only cause you have so much hit rating so can afford to loose some from banking bonebreaker in favour of the expertise on facelifter. Its npot an upgrade, just more a sidegrade. The lastword isnt worth a moment of your time, the ultimate survival weapons is still the anuburak 10man HM armor weapon, and the best all round weapon is the Lich King one.
If i were you and got a mark, I would probably get it for shoulders or chest first, then head, finally gloves (while hoping i get gloves in VOA first). Everything else in your setup looks fine, but why did you use +10 stat gem? seems waste of time for a survival tank tbh. Also consider dropping focused rage and polish of shield spec instead, you should not really need focused rage any more, imo its just a relic from a bygone era, and shield spec has more benefits.
