The folks at VisualEconomics have put together an interesting graphic on the "Financial Habits of American Youth." I could see this being a good class starter for almost any personal finance class when school resumes in the fall.
It doesn't offer a lot of starting points for traditional topics, but it does get a sense of how students view their finances and where they get their information. I envision a "pre-test" or "survey" format to allow you to see your students' responses and then compare to the results on the graphic.
Please offer other suggestions.
