For the most part you seem easily well geared enough for most of Kara (I personally don't know how well geared you should be for Prince and Nightbane as my warrior just hit 70 as well).
Your spec, though, kind'a gets me. It's like you want to do prot-DPS, which just doesn't work well at all. By and large, UW isn't all that useful for tanking due to the fact that you should be getting hit hard enough already to maintain an adequate amount of rage. Imp. rend is entirely useless, as the ability itself does such a miniscule amount of damage that it's not worth it to even use while tanking 99% of the time (I think the last time I used it while tanking was in VC...). Overpower requires battle stance, so imp. OP is automatically out. Deep wounds and impale, while nice, aren't really worth it for the other things you could be getting for the points. Improved taunt also isn't all that great in Kara, due to the fact that you and your DPS should have a threat meter and thus be able to see how close they are to pulling aggro from you and slow down accordingly.
Places that you could spend those 14 points (rend, OP, deep wounds/impale and UW) are:
-Finish out 1h weapon spec, as this effects how much damage your slam will do, and thus corresponds directly into more threat.
-Vitality, more HP and more threat from the strength (as well as a little more mitigation from the blocking aspect of strength, though it's not all that much)
-Shield Mastery: More mitigation's always nice (don't tell this to my brother, though... he hates that talent :P)
-Devestate. Since you now have that many points in prot, get it.
-2/5 (or 5/5 if you have a warlock to put on CoRecklessness and the melee DPS to justify the loss in caster damage) imp. Demo shout, as this will basically kill all of the bosses AP (I think they have 300?).
Other than that I can't really think of anything off-hand.
Oh, and also you messed up on the link to
your armoury. :P
