Hi -
I've attached a basic Final Cut course to this thread -- I'm not a FCP user myself so I can't advise, but maybe there'll be something useful in there, or perhaps a regular FCP user/guru will have a suggestion..
There are quite a few other FCP courses available as well, in case you see something in one of their TOCs that you think might be helpful..

While this isn't a Final Cut Pro tutorial, it should show you the basic principles — which are a little time consuming.
