Reddit mentions of Apple Pro Training Series: Final Cut Pro 7

30 days is plenty of time to become proficient with Final Cut. As others have said, the versions can be very different, so you would really need to train for the specific version you will be using.

Either way, I would recommend going through the official training book for the version you will be learning - most likely FCP7 or the more recent FCPX

The book for FCPX was printed before a number of big updates, so the info may be a little bit outdated. Also, the basic book doesn't go into multicam editing, or green screen, or any advanced technique; you would need to go through the advanced book to learn those aspects.

If you can afford a Macbook Pro and the Final Cut Pro Software this is a great book that'll get you through the basics easily. I switched from Avid to FCP using it and it was pretty painless. Stay away from FCP X though. It's gonna be a while before they get that one where it needs to be.

As far as the creative aspect of editing the only real way to learn any filmmaking craft is to do it. But there are some great books that did a better job than any of my professors did. This is the best book on editing I've come across. I just got it recently but it would have been really nice to have it back when I started. And this is my favorite directing book. It's written by a film professor but it does a beautiful job of breaking down the creative process. And The Film Director's Intuition is a great place to start with how to work with actors.

For lighting I'd recommend Matters of Light & Depth by Ross Lowell and Film Lighting by Kris Malkiewicz.

Also indispensable is The Pocket Lawyer For Filmmakers.

Those are all great books chock full of practical advice. And if you're interested in screenwriting Story by Robert McKee is pretty amazing. People shit all over that guy but nobody teaches story structure better than him.
