Jame's Alliance Leveling Guide is a fantastic leveling guide for alliance that I use all the time, very detailed with lots of pictures and every thing you need to coast to 60 for alliance.  This is found at wow-pro.com.  James alliance guide is free, however if your willing to spend a little money you can obtain a much better leveling guide for alliance that is much more detailed here at this site.

The two most detailed leveling guides for World of Warcraft currently are Brian Kopp's 1-70 alliance guide(mentioned above) and Joana's Horde Leveling guide.

Both of these guides are quest-grind type leveling, which is the fastest way to level up in world of warcraft. I have been using both Joana's and Brian's leveling guides for quick reference on quests to get, and the order to do them, and when to do the instances, both are extremely helpful in your leveling efforts.
