The Joy of Clojure goes into to Clojure philosophy and explains the "Why?" of Clojure. Clojure Programming is divided into five parts, and parts III and IV provide a good overview of how to set up your environment and structure projects.
But the best book for learning the language is Programming Clojure (http://www.amazon.com/Programming-Clojure-Stuart-Halloway/dp...) by Stu Halloway. Stu works alongside Rich and understands Clojure at a deep level, but he's still in tune to the beginner's mind and is able to clearly explain concepts and provide the context you need for the ideas to resonate.
