Search youtube for a bunch of tutorials.
The main thing is to learn all of the simple things in and out.
Ableton has a free demo with an awesome training class built right in. Only downside is you can't save/export. But it will teach you how to use a lot of things like: LFOs/Reverbs/High&Low Pass Filters/ and a whooole buch of things.

Didn't mean to sound so dickish in that first post. I record music for a living so I know what it's like to be new...All the old peeps try to keep you down, and they shouldn't. If you download that demo, and follow the tutorials you'll be on your way to making solid beats in no time. And I'd bet money once you finish that, you'll by the full version so you can save your work. That is one awesome program.
