#1 WotLK Leveling Guide
Extreme Leveling 1-80 Leveling Guide
This guide is a fantastic way to get started on your journey from 70-80 in the WotLK expansion. It includes FREE updates, an in-game leveling addon, and one of the most highly detailed leveling guide that I have ever seen.
Also included, besides the Horde & Alliance leveling guide is a really nice 55-80 Death Knight leveling guide.

#2 WotLK Leveling Guide
Zygor's WotLK Leveling Guide
This guide is also one of my top choices due to the fact that it is a 100% completely in-game leveling addon guide. That might sound a bit scary but rest assured the leveling addon is the best in-game addon I have ever seen. It's the only one that I know of that doesn't rely on any other addons in order to work. It works by itself and doesn't take up a lot of memory or room.
