Have you found your way to the Arizona Trail Association's website yet? It has everything you'll need to know to make the best of your hike:
There, you will also find links for ground transportation at both ends of the trail.
Of course, many other folks here have their own wealth of experience with the trail and will, no doubt, have helpful info as well.
All the best on your adventure!
