The first thing you should do is install the Apple Developer Tools. It's included on one of the installation discs that came with your Mac, or alternatively, you can download it from Apple's website. Among other things, it includes gcc (the compiler you'll be using), and Xcode (an integrated development environment). I'd suggest starting with Xcode, as the interface makes it simpler to compile and run applications.
As for learning C - there are lots of resources in the C forum here, I'd recommend starting with a Hello World program and working your way up from there. Not having any programming experience might slow you down a bit, but there's nothing in learning C that absolutely requires prior programming expericne -- it just helps.
