OK... calm down.
You don't move anything.. you use an external drive when you record... your song files, newly recorded audio, go onto the external drive, nothing else.
I suggest you sign up for a month of "all you can watch" tutorials for $25 at Mac Pro Video. They can really help you get a handle of what you need to know, mr "no tech dude" ;-)
Trying to do this stuff without knowing the basics is not really such a good idea, though it can (and in fact often is) done. The manual is huge and doesn't really tell you what to do, rather it describes what this are. The smaller intro to Logic manual is better.
Either way, try and get the month long tutorial from Mac Pro Video (I have no affiliation with these guys, just so you know). I guarantee you that if you spend an hour every couple of days at it (watching a tutorial and trying out some of the things you learn), you can get pretty comfortable on Logic.
BUT I can tell from your answers that you really need to invest some time into learning and understanding the basics... really, you should (and I don't often use the word "should")...
Apple and Peachpit press make some great books as well. David Nahmini's Logic 9 beginner book is awesome (I do know David, and I have been lucky enough to have taught people from it through him in the past)... It does assume you know the basic's first.
Have you ever looked into the "help" menu from the desktop menu? You can really learn allot from that as well...
So, breath, relax, spend some time and learn this stuff... it's not that hard BUT it does take a small investment in time to learn it, and a while working with it before you will understand it.
