I use Lightheaded and DoubleWide myself (always remember to disable the Lightheaded mods you aren't using, so if you're 1-20 alliance, disable 20-80 alliance and all of the horde ones, they take up valuable resources).

But for Quests I love love LOVE my QuestFu Fubar plugin. It's the greatest. I'll check out Tomtom -- I've heard it's good.
