Um, what specifically about FCP5 do you need to know? It's a complex application that does a million different things. Do you need just basic use? I'd strongly recommend the Apple Pro Training Sereies, Final Cut Pro 5 book rather than on-line tutorials. Nothing will get you up and running better.
Some of us have tutorials for free. I write a monthly column called "Cut Lines" in Event DV magazine for Final Cut Studio. You can go to eventdv.net and do a search for "Cut Lines" or "Ben Balser" and find them all. We began at the begining and have been getting more advanced from there.
