Super-heating is a great idea. Approximately 60k/h per hour, not too expensive, and you get magic xp. I assume it would only take you 5-7hours from your current level, to get to 65.
The Knight's Sword quest is an easy 13k smith xp. Takes 20 minutes if you buy all the items from ge, only need 10 mining. Above suggestions are both good, superheating is nice for magic + decent smith xp.
