Distiller does not include bitmapped fonts unless the fonts in the PS
file are bitmapped.  Conversely, if the fonts in the PS file are bitmapped
it will include those instead of outline fonts.  The choice of bitmapped
versus outline is made by whoever or whatever produces the PS file.
PDF can support either format, although the Acrobat Reader does not
show up bitmapped fonts well at all.

Distiller does not convert vector drawings to bitmapped images.
Again, the decisions has been made by the time you feed it PS.
Distiller *can* optionally reduce the sampling rate and compress
the bitmapped images.  But it will never turn vector drawings into
bitmaps.

Not at all.  Distiller understands PS level II.  No need to dumb down
your PS. It is up to the printer driver on the Reader side to use
PS level I or PS level II whichever is appropriate.  Certainly there
is no conversion to bitmaps when meeting level II code.

Maybe tune in to comp.text.pdf?
