As "new to horses" myself, I have the same problem. I started with the online resources already cited, but I also got "Principles of Conformation Analysis" by Deb Bennett. The photographs therein suck big time (grainy black-and-white), but you can get something from the text, I'm sure. ISBN: 9781929164608

I am also painfully aware of the saying, "Of 1,000 people who can pick out a flaw, only one can pick a horse."
