PanZoomPro is a generator that works inside FCP. It beats the pants off FCP’s motion controls. Downside is it can take a while to render. For your basic Ken Burns style slideshow, Fotomagico is my tool of choice. You can put music or sound in it to time to, and it is very fast. Dean’s workflow is good too, I’ve never used Automatic Duck, but I’ve seen it, it’s pretty cool. Fotomagico is your cheapest, easiest, fastest solution.
