Subject: Amalfi coast w/luggage?

I am planning a trip to Italy which includes the Amalfi coast. I would like to know if anyone has taken public transportation (buses and ferries) with luggage in tow. I am trying decide between hiring a private driver or taking public transportation. My plan is to take buses and ferries from Sorrento to Salerno, then train from Salerno to Paestum then train from Paestum to Cosenza! Has anyone done something similar? Also does anyone have a favorite Sorrento private driver they could recommend? thanks!
