The urw symbol name is certainly different, and that is the only real 
font you have (the type 1 font, afm files are just the metrics, you 
don't need them, the tfm files are metrics, tex needs them). It is the 
combination that makes it hard. an automated way is preferred. The 
library fonts will never be used by (pdf)tex.

This requires a trip to the terminal, I hope you're comfortable with 
that, and some tools might need to be installed -- I can't recall which 
ones came with i-Installer and which ones I installed myself. (Google 
can find these tools).

- Produce the ps file with all fonts included. Don't forget ro remove 
the page number in the (La)TeX file.
- use ps2eps to get the sizes correct (this will take care of the 
bounding box).
- use epstopdf on the resulting file.

The pdf you get now should have the right size, and include all 
characters. Further processing can be done with pdflatex, and font 
troubles will be a thing of the past. If the fonts turn up in the pdf 
without being subsetted, they will be larger than needed: look fot the 
multivalent tools (on sourceforge) to compress the pdf files, one of 
the options is to use subsetting on the fonts.
