I would suggest to put at least 1 Talentpoint into Improved Judgements to reduce the Cooldown of your Judgements by 1 Second, so it will fit into the 969-Rotation, which you should use (and find out about, if you don't already know). You should not use the Glyph of Consecration for the same reason: it not only makes consecration stay longer, but increases the cooldown, which will interfear with your tanking rotation.
Other than that it's okay, though I would put some more points into threat-generation abilities. But that's really more a matter of taste and the threat requirements of you group.
this is the setup I use http://talent.mmo-champion.com/?pala...1,wHa-e3,10596
Its pretty much the standard spec. Some people like to take the 5 points out of Divinity and put them in Seals of the pure for the extra threat but that's a matter of personal preference.
