Have you tried the command above (minus the extra space!) with IE? That's all I had at work yesterday, and it looked fine.

I use Firefox at home as well though, and since nobody can be expected to make do with IE if given a choice, I fiddled some more with pod2html (following BrentDax suggestion with the "c|").

1.) To get the stylesheet to link correctly, try the following option (I'm assuming you installed your ActiveState Perl to C:\Programs\Perl):
--css="file://c|/Programs/Perl/html/Active.css"

2.) As for the links to perldocs, the "--htmlroot" option allows you to prepend what you need to the links. In combination with --podpath and --podroot, try:
--podroot="/" --podpath="Programs/Perl/html" --htmlroot="file://c|"
