I started with Lite-C Workshops.
That give me the start I needed.
Then I looked at some of the examples based on the kind of game I was interested in making (http://au.conitec.net/). When I get stuck, I consult the Lite-C manual. If I am still stuck, I post on the forums.

If you are now starting out, it would be good to start with variables, and panels, and move from there. Start with Lite-C Workshops.
