I took a four day class with Diana Weynand, who wrote the Final Cut Pro 6 book for Apple. It was pretty expensive (around $800), but I did learn a lot. My local community college (Tucson, AZ) has a semester long class - check community colleges and universities in your area. I also learned a lot just by going through the Weynand-authored book and doing the exercises (it comes with a disk of footage to practice with in the lessons). Good luck!
