If you're sick of SM, you could boost through quests.
Zones like: STV, Thousand Needles, Dustwallow Marsh, Desolace, Alterac Mountains.
Honestly, I'd think just doing SM to 45 will be faster.

You can do ZF, particularly with an unmounted Bear, as your immune to the Hex/Polymorph.
But you cannot use your mount.
There's a pretty good, "How to boost in ZF" video, in the video section on www.isboxer.com
I'd personally just stay in SM, but there are options.

I like Stratholme (the gate that you need a key to enter, rather then way on the NW corner of the zone).
Usually go 45-55 there.
Then 55-60 in Ramparts.
If you want to boost beyond that (RAF 3x exp's done), you can go Underbog, and then Black Morass (don't start the event, in BM).
