However, a question: does the PPD I use to generate Ps for Distiller when creating a pre-press PDF have any relationship to the PPD the print shop  uses when converting that PDF for plate-making? If not, then there is clearly no reason for me to use a Herkules PPD, or any PPD other than the Distiller default.

To directly respond to your question and response:

"Does the PPD I use to generate Ps for Distiller when creating a pre-press
PDF have any relationship to the PPD the print shop  uses when converting that
PDF for plate-making? If not, then there is clearly no reason for me to use a 
Herkules PPD, or any PPD other than the Distiller default."

That is correct. There is NO relationship between the PPD used to generate
PostScript for distillation into PDF and the PPD used by the print shop
as part of process of producing a plate via PostScript from the PDF file!
And yes, there is clearly no reason for you or anyone else to use a PPD
other than the Distiller PPD provided with Acrobat.
