I use a very similar one to this for levelling... its great - zero downtime, and the more mobs you aggro, the more damage you put out...

I would start by putting the first 10 points into Justicar for survivability until you get Mien of Honor and Doctrine of Bliss. From there, probably points into Inquisitor to reach Soul Drain. Then some more into Justicar to get 3/3 Vengeful Justice - then start on the Shammy tree.
Its a lot of fun, and makes levelling quick. Just watch out for ranged mobs, as they can pick you off whilst you hammer on the melee ones.
