A few comments on the spec, Blood in the water is totally useless in the current incarnation of pvp though with the change in cata it will be hard to say if it will be or not, and thick hide is an extremely iffy talent as other things are better, being primal madness and endless carnage, which both are close to 100% needed. in pvp especially you can't always TF when it works best so having it not waste even more energy most of hte time is rather key, then add into that it lets you use abilities in bear mroe simply and it's golden, and endless carnage makes your hardest hitting ability get another tick. Rake hits significantly harder then rip, the main difference is duration so giving it a longer duration makes our best pvp ability even better.
On the topic of racials the way you're using shadowmeld makes it awful and rather worthless, and makes both warstomp and the troll racial far better in pvp. The main use of shadowmeld in pvp is if timed correctly it'll dodge a spell.
