The site wwndata a sub-site of www.worldofwar.net has started posting some very interesting maps of the World of Warcraft. The maps are individual maps of each zone in WoW and show where quests are given out, what level and what faction they are for. These are a very handy reference to each zone.

Currently the maps only show the start location for each quest. It does not mention if they are planning to include the objective areas for each quest, but if they do the maps would become indispensable while questing.

You can check them out here.
