I know prot pallies who tank Ulduar Hardmodes who will tell you otherwise:-3) Divine Sac /guard are useless points as prot. if you're tanking you should never be using sac. I've yet to find a point where wws /matrix has shown me where sacred shield has helped me avoid a death. this is progression + hardmode tanking, as well. I find the talent useless. Lastly. Crusade is an overall threat and damage boost whereas SotP is only vengeance. I personally recomend switching. other than that, the tallent build is on target, if not exactly what it should be for ulduar.
The point of getting Divine Sanc/Guard is to get the inproved Sacred Shield.  The Divine Sanc itself is only an added perk you can use on fights you are not MTing.
Anyway here is a friend of mine's armory:

I have witnessed him pulling 2.5k+ while tanking in a 5man, on a single target.  I'd say prot pally DPS is up there now.
