What is the recommended transportaion going south? Is there a way to pick up a train across the boot?

Depends what you mean by 'outh'. Either get the Circumvesuvia train back into Naples and catch a Trenitalia service from there, or possibly use the Circumvesuviana to go to anothr town (e.g. alerno) and then travel onwards by Trenitalia. Depends entirely on where you want to go.

What do you mean by "across the boot". Where exactly are you trying to get to? If you truly mean South, e.g. to Reggio, you wouldn't need to get across the peninsula at all. If you mean Brindisi, you can turn Eastwards after Salerno. This rail map makes it clear: http://www.raileurope.com/us/common/rail_map/italy.htm

Yes, a clue about where you want to go would help.
In much of the south train connections can be problematic for smaller destinations and you will need buses, and some places in Puglia and Basilicata are served by independent rail lines that you won't find on the Trenitalia website.
Main 'cross the boot' train routes would be Napoli-Benevento-Manfredonia, with connections there for points south in Puglia, or Battipaglia-Potenza("The Capitol of Nowhere")-Metaponto-Bari, or Reggio di Calabria-Taranto-Bari.
