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

That's all I can think of.  HTH
