Hi there,
Yep, ActiveState's implementation of Perl is great and it comes with some nice online documentation for all the important perldocs, modules, etc.
Another Win32 implementation you can look at is the one that's part of the Cygwin distribution at
http://sources.redhat.com/cygwin (I believe.) I haven't used it as much as ActiveState's implementation but should get the job done.
