Im interested writing television cartoons but I know nothing about scripts at all..where should I start? Is there anywhere I can find definitions to somethin like an "Act" or anything like that? I'm starting from the very very beginning

I have a trial version of Montage for Mac, and it comes with a bunch of writing templates but I'm not sure which I want to use. Does anyone use this program? Heres a link to show the screenshots of the program
http://www.marinersoftware.com/sitepage.php?page=111I was suggested Montage or Final Draft and I like the way Montage looks a lot more, but I just don't know what I'm looking at!
I usually learn from examples or in this case I guess it would be looking at a script from Family Guy or something so I can see how it all looks and its presented.
This is all completely new to me but I have been looking around for forums and there doesnt seem to be much communities discussing info on scriptwriting.. but its nice around here!
