I don't know warriors, but I do know a little something about healing mages (now, thanks to this forum). For an awesome spec (at least for now) I suggest reading over This post
The current spec I'll be using at 50 is THIS
(the rest of the points are preference)
At level 32, it should look something like THIS
Basically, as you level past 32, put all the points into warlock until you're at 30 in lock.
Dominator is used for Transmogrification.
There are other options, this is the one I'm going with, but if you read that link you'll get a good idea of the two main specs (either Chloro/LockDominator or Chloro/Lock/Archon)
