Howdy! Some nice addons I'm using to level my characters are Tomtom, Tourguide and Lightheaded. One of the addons is a ingame leveling guide (Tourguide). Tomtom makes you have a big arrow (like the taxi console game from the 90's) that points you where to go and the Lightheaded addon takes all of the coments from wowhead ingame and when u click a quest in your questlog you can see the comments(and when you click the coördinates on the comments, Tourguide automaticly sets a waypoint and guides you there). You can easily skip the gathering guests and just do the kill quests. You can find all of the addons on www.curse.com .

Hope those addons might help! Triple quest exp is always way faster than grinding (10k exp would take you more time when just killing the stuff instead of getting that for each quest).
