Rex,
I append below a compilation of 2 older messages that explain
how to get round the ligature problem.
I think it will answer all your questions.
The virtual font solution was sent by Timothy van Zandt.
Be careful with commenting out the G option, because the
bottom half of large delimiters will not be printed if you
sent the file to somebody who uses Acrobat for Windows.

======================================================================
1) If our file has only text, we can use a Postscript font with
the flags -Ppdf -G0
2) If our file has both text and math with large delimiters, then
we can use Computer Modern with -Ppdf -G
3) We CANNOT use a Postscript font for the text and Computer
Modern (or Euler) for the math, because if we try to get rid
of the large delimiter problem with -G, we lose the fi, fl
ligatures in the text font.
The misprinting of large delimiters is a bug in the PCL printer
driver for Windows Acro Reader 4.0. Acro Reader 3.x has its own set of
bugs having to do with control characters positions and that benefit
from the same approach.
The new Acro Reader 4.05 fixes this problem and I have not yet
heard of control-character bugs for this reader. However, most people
do not have this version installed.
To get around problem 3) above, and be able to use -Ppdf -G
-----------------------------------------------------------
Another option is to switch back to an old-fashioned encoding for
the Adobe PostScript fonts. But remember that purpose of the reencoded
PostScript fonts was to get access to various glyphs that are useful
for foreign alphabets.
Here, for example, is the unix script I use with teTeX 1.06 to create
Helvetica virtual fonts with the old fashioned encoding:
---
afm2tfm phvr8a.afm -u -t dvips.enc -v phvr8a.vpl tfm/rphvr8a > tvz8a.map
afm2tfm phvro8a.afm -u -t dvips.enc -v phvro8a.vpl tfm/rphvro8a >> tvz8a.map
afm2tfm phvb8a.afm -u -t dvips.enc -v phvb8a.vpl tfm/rphvb8a >> tvz8a.map
afm2tfm phvbo8a.afm -u -t dvips.enc -v phvbo8a.vpl tfm/rphvbo8a >> tvz8a.map
vptovf phvr8a.vpl vf/phvr8a.vf tfm/phvr8a.tfm
vptovf phvro8a.vpl vf/phvro8a.vf tfm/phvro8a.tfm
vptovf phvb8a.vpl vf/phvb8a.vf tfm/phvb8a.tfm
vptovf phvbo8a.vpl vf/phvbo8a.vf tfm/phvbo8a.tfm
---
The files tvz8.map and the .vf and .tfm files have to be put in the right
places,
tvz8a.map then needs to be included in the dvips config files (p+ tvz8.amp),
and then you need to create .sty file that sets up the font for TeX. For
example,
this one is for the Helvetica fonts, scaled to match the x-height of the cmr
fonts:
---
