Icecrown leveling

Since the leveling process is sped up, are there any preferred ways to level up, like skipping quests and such? I have, for the most parted used zygor's guide for leveling, but this seems irrelevant now. Any help would be appreciated

Here is for horde and this for alliance.

I must have been blind, because I did do a search, Just must not have looked hard enough. Cheers !!!

It's more like knowing how and where to find it, cheers buddy.
