You might try going back (as far as Wizard City) and pick up all those side quests you skipped. And Crab Alley on Trition Avenue, and Wysteria, also give a lot of XP to help with levels.
For all of the new wizards out there, I hope you are reading these posts. You might not want to be bothered with side quests because you're in a hurry to get to Dragonspyre or Celestia or whatever. But it won't help you (like this post), if you aren't the right level.
