Having never tanked blood, I'd probably go with something more like this.

I can see ditching your self healing talents at 80 because you can expect your healers to be up to par. When leveling it's harder to find good heals which is why I chose blood. Anyway, I do plan to respec to something more plausible at 80. What's up with str and why is it such a benefit to tanking? Is it just extra dps to improve threat?
