Eye posted a spec which should definitely help with leveling. Some of the big things he picked up to help out are an increased mana pool (less downtime) as well as instant ghost wolf (mob to mob quickly or that needed escape tool). Typically you should think about the things that will benefit you the most when leveling. You don't need to worry about having a max dps spec since most of the mobs die so quickly anyhow. Think about what will keep you killing and moving along.
