Seeking Wisdom: From Darwin to Munger = http://www.amazon.com/dp/1578644283 = a deep read, mostly focused on cognitive biases
Poor Charlie's Almanack = http://www.amazon.com/dp/1578645018 = a big coffee table book of his speeches and essays, good for leaving on the kitchen table to read over a meal
I think if you order the books directly from Charlie Munger's company, the proceeds go to charity: http://www.poorcharliesalmanack.com/
Munger's concept of mental models is the basis for my book ("The Personal MBA"), which comes out in January. The project started because I was looking for a comprehensive treatment of Munger's models, but couldn't find one.
Munger's models also tend to be very clearly focused on making investment decisions, which is great, but tend to overlook how to start / grow a business, so that's what I set out to create.
This approach is now the basis of my work with my clients and course participants, with huge success. Mental models work wonders for people with little knowledge of a topic - they're a great way to teach people something useful quickly.
