I found an interesting site with interactive maps of Azeroth and Outland, called MapWoW The neat thing about it is that it uses the Google Earth API. It’s good for finding flight paths, treasure chests, mining and herb points. However, it doesn’t have locations of quest NPCs and objects. This site is good for miners and herbalists, as it has coordinates to points for picking or harvesting. A great companion to the addon, Gatherer.
