Izzy Video has a decent set of tutorials on FCP-X. If you are going to edit in FCP-X, do the entire project there (FCE projects cannot be imported into FCP-X, at least not yet).
In fact I also have a MacBook Pro with FCP X loaded with a bunch of old clips of my young daughter that I shot many years ago. These are still waiting for me to start editing, but I have first to learn some basics of FCP X. Al, if you have any suggestion on how to start the move... please !
Thanks a lot
