The third one is a good, solid adventure that isn't just 'teach the system' but an adventure that stands on its own. An adventure path is probably a great idea, but not necessary. A good starter adventure is essential. My guess is that most people are going to play that first adventure, so you want it to be the best introduction to the system.
