The Basics

I'm more of a classical pianist than a tech guy, so I'm really just starting out on all of this. I read some of the FAQs on the website. But is there anywhere I could go to learn the very basics of working with one of these keyboards and the basics of patch design? Things like aftertouch, attack, and such? Other things as well of course. So if you have any links to good information or could tell me where to go to find it, I'd be indebted to you.

Thanks
