The easiest way to get started is to open a DOS window. Change to the directory of your perl script and type 'perl scriptname.pl'. I like this because I can rapidly test by hitting F3 (in win9X) or up arrow (in 2000).
You can also check the activestate docs on how to setup your extensions (sorry don't remember off the top of my head)

PS don't think of your self as a dumba** we've all been there, picking up the Llama book is best step forward you can make.
