Well, I've just said it in another post, but you could do a lot worse than follow 'The Challenge' through...
It will teach all the basics of keyword research, strategy and setting up some simple sites. At least then you'll have a framework for learning in more detail:

It ain't 'blackhat' - but if you don't understand these ecommerce basics then most other stuff is a waste of time. Then you can come back here and 'lurk' and read for a few months, trying out things to get a feel for them.
