Hi terrapin -
Unfortunately, databases can be a bit of a complicated topic - it'd be difficult for us to duplicate (successfully) the heaps of information out there. Some of it can be kind of dense, but we can definitely explain it should you find the need to ask questions.
If you're new to MySQL or SQL in general, I'd check out the following tutorial:
...it's the best I've seen on the 'net so far.
If you get through that okay, and you have some extra bucks to spare, I'd suggest getting the O'Reilly MySQL book (you can find it on Amazon or your neighborhood book store). It goes into more detail, but is still pretty plainly written - as plainly written as a book on the topic can be, at least.
And if all else fails, contact support with your questions or post them here. :>
