Ruby On Rails and MySQL

So I started learning Ruby On Rails last week in preparation for developing OpenThinkTank.org. I must say, I'm quite impressed with this system so far. Ruby is a very simple language, and Rails is incredibly powerful, yet still simple to use. MySQL on the other hand, is much harder to learn. I can't seem to get the GUI working properly and the Rails book I'm using is all command prompt, so when something goes wrong, I have no idea what's happening. Anyone know of a good MySQL reference? I'm usually a fan of the O'Reilly books, so this one might be good.

Managing and Using MySQL, Second Ed.

Any thoughts?
