There's a lot of generic Win32::OLE info in Using Win32::OLE and Excel - Tips and Tricks, and it has links to some good books on the subject (I have the Roth Book myself).

As for exploring the MetaFrame object model, do try out the "Type Library Browser" installed with ActiveState Perl (in ../html/OLE-Browser/Browser.html, its installed as a HTML link in the perl program group).
