Four things come to my mind:

1) I use ps2pdf (from the gs 5.0 package, the non-free version of
Ghostscript) for all ps-->pdf conversions.  The generated PDF is a bit
big.  I don't have color figures, so I don't know if this will fix
that problem.  I have, however, had very good luck with greek letters
and pretty advanced math (the stuff was for a Laplace Transforms and
Advanced Differential Equations course.  Quality impressed the
lecturer quite a bit, too :{)

2) You may want to try using postscript fonts only to get rid of the
fonts problem.  I know that those fonts (Times, Helv, etc.) are
included with PDF viewers, and serve as "base" fonts.  Just
\usepackage{pslatex}, or process the LaTeX file with pslatex' instead
of latex'.

3) There's apparently native support for PDF in TeX in the latest
teTeX packages.  I'm not very familiar with it, mind you.  It seems
quirky--accepts only PNG input as graphics, postscript fonts only,
etc.  But the PDF generated may be better than the one from ps2pdf.

4) If you're using xpdf as a PDF viewer, you will _not_ get output
that looks fine.  xpdf does not understand embedded fonts, AFAIK.  I
use gv for viewing PDF, and people tell me it looks fine in Adobe's
reader.
