I'd guess that the format of your config file is not 100% correct. Are
the "font" tags really configured for the PCL section, too? At the
moment font configuration needs to happen for each renderer separately.

You can ignore that.

See comment above.

xmlgraphics-commons-*.jar is missing in the classpath. But in FOP 0.95
you don't need the XML font metrics files anymore. See:
http://xmlgraphics.apache.org/fop/0.95/fonts.html#custom

No, except that the config file could be wrong.

You said you're on .NET. So does that mean the .NET version of SAXON?
Generally, it doesn't make any functional difference which XSLT
processor you use. You can even use Microsoft's. In terms of performance
the choice of XSLT processor and the way you combine XSLT + FOP can make
a difference. Usually, you lose some performance if you have to
serialize the intermediate FO file because it just has to be parsed
again later.
