World of Warcraft Speed Leveling Tips
Skip the looting. On my way to 70 I looted everything and skinned everything skinable. You get the loots, but it does slow one down. If you don’t need the loot or skins then skip the looting. Just kill and move to the next. Youi’ll save a lot of time over those 70 levels.

Gaining reputation with your home faction provides access to discounted prices at their vendors, and certain Wrath of the Lich King reputation achievements.
