Our talent, Improved Judgement, allows the judgement cooldown reduces it to 8, but it can be no less than 8 seconds per cast.
Haste shouldn't affect anything who's actual cooldown is >= GCD. Haste only reduces the global cooldown of spells, not their actual. So Holy Shield can only occur once every 10 seconds. Consecration can only occur once every 8 seconds.
Some of that will change with the WotLk though, just FYI. Bear Mangles will happen faster, Holy Shield will happen faster, etc.
