What you're doing is basically boosting the lowbie through quests - which is what many do with mages/paladins to boost lowbies through instances for xp. I don't believe there is a specific 'guide' for doing the quest boosting - I use Jame's Alliance Guide for following quest order while playing as a group. There are a few posts here about instance boosting though. I'm not sure how efficient quest boosting is compared to just plowing through instances since I haven't tried it much.

Since you seem to like boosting through quests - just use the free guides at wow-pro.com like Jame's.. and that'll keep you entertained and efficient with xp.
