Starting Out… Which Path to Take?

So I’ve decided I’m going to start out trying some PPC affiliate marketing. I don’t know whether it would be better to just start by experimentation or get some solid knowledge through some courses.
Right now I know how to setup Adwords campaigns and all… is that enough through to start making money?
Or should I join one of these courses like PPC Coach or Ubercamp. Or can someone suggest a quality ebook maybe that might help, as I’m not too hesitant to invest in a solid guide.
I appreciate your suggestions!
