This is a guide for Horde Players Level 1 - 60. Although I have not used this guide personally I have heard good things about it and it looks worthwhile IMO. Only flaw I see right now is that it is from a warlocks perspective, but the author claims that it should work for all classes. Check it out if your interested! Its free!
