I'd start with something like this. Especially if you're going to use the dungeon finder a lot, getting your hands on Hammer is really big.
Then start working your way down to this. You'll need a couple of filler points, but basically, you want to go as far down into the tree as fast as possible. You'll then need to go back to the lower levels to advance further, since there's not really much of benefit in Tier 5 talents for leveling.
At the end of the prot tree, you should have something like this.
