I had the saem experience, but rather than going back, I have been working
with texfont.pl and the below mentioned documents describing the new font
handling.  The examples in showfont.pdf were useful in checking that
things were set up properly.

I still don't feel that I understand the new mechanisms well enough
to make sensible decisions for the following questions (knowing that
the answers differ depending on what fonts you normally use, how much
use you make of LaTeX, etc.):

0.  what options should be enabled in cont-sys.tex?

1.  what should pdftex.map contain?  Clearly this depends on what options
you use from cont-sys.tex.  I want to be able to use pdfelatex, but I
prefer to load map files in each document because it helps me to keep
track of what fonts are used.  My current thinking is that pdftex.map
should consist of just the cm portion of bsr.map with original-ams-logo
.map, etc. loaded via cont-sys.tex.

2.  what fonts should I install using texfont.pl?  For testing, I
have installed the URW fonts using the ber names for the input files
and texnansi encoding.  I created a Times-Roman-Caps font, but to use it
I ended up putting copies of type-syn.tex and type-enc.map in the
document directory.  In type-enc.tex I added the line(s):

  \definefontsynonym [Times-Roman-Caps]
  [\typefaceencoding-utmr8a-capitalized-800] [encoding=\typefaceencoding]

and commented out the line:

%  \definefontsynonym [Times-Roman-Caps]        [t1xsc] [encoding=ec]

In type-syn.tex I added the line:

  \definefontsynonym [SerifCaps]        [Times-Roman-Caps]

inside the "\starttypescript [serif] [times] [name]" block.

In retrospect, replacing the ber names with the actual font names (e.g.,
NimbusRomNo9L-Medi instead of utmb8a) might have been the best approach.
Since the font files are stored under directories with the vendor name,
the fact that the ber names code for vendor seems redundant.  In practice,
however, the ber names are used in type-enc.tex.

Here is how I installed the URW fonts on a unix system with ksh (note
that helvetic might better have been helvetica) with texnansi (the
default) encoding:

$ awk 'NF==3' /usr/freeware/share/texmf/fontname/urw.map > urw.map
$ export d=/usr/people/gwhite/share/ghostscript/fonts
$ for f in avantgar courier palatino zapfchan helvetic \
           symbol zapfding bookman ncntrsbk times ; do
  mkdir $f
  case $f in
  avantgar) ber=uag ;;
  [...]
  esac
  grep ^$ber urw.map > $d/names.map
  cd $f
  # copy the font files (ghostscript names from the 3rd column)
  # to the installation directory (using ber names from 1st column)
  awk -v d=$d '
   {printf("ln -s %s/%s.afm %s.afm\n", d, $3, $1)}' names.map |sh
  awk -v d=$d '
   {printf("ln -s %s/%s.pfb %s.pfb\n", d, $3, $1)}' names.map |sh
  # install fonts into $HOME/texmf-fonts
  texfont --fontroot=$HOME/texmf-fonts --ve=urw \
          --co=$(basename $PWD) --ma --in
  cd -
done

$ cat avantgar/names.map
uagd8a  URWGothicL-Demi     a010015l
uagdo8a URWGothicL-DemiObli a010035l
uagk8a  URWGothicL-Book     a010013l
uagko8a URWGothicL-BookObli a010033l

I added a Times-Roman-Caps using:

$ cd times
$ texfont --fontroot=$HOME/texmf-fonts  --ve=urw \
          --co=$(basename $PWD) --so=. --caps=default utmr8a

Next time I may use names from the 2nd column.
