Getting into painting. Good links/info?

Paint seems to be a place car guys are apprehensive to go to.
Naturally because of that I want to know more about it and start doing it this summer (also my 91 could use a fresh coat.) I am starting to buy up body parts (each plastic and metal) with the idea of practicing and learning to paint them PROPERLY. I am buying an air compressor and spray guns in the next few weeks and other things needed for a home spray booth.
All I need to know now is how to properly use those tools and the perpetration of the body parts (IE: sanding) for paint.
I have been up and down the F.A.Q pages but I did not really see any info about it.
I just know that there is much much more to know involving painting, and if you guys know of any good info let me know.
Thanks
