The best prescriptive book that I have found has been: http://www.amazon.com/Zen-Training-Philosophy-Shambhala-Clas...

Additionally I find that reading a good translation of the Tao helps, my personal favorite so far is: http://www.amazon.com/Tao-Te-Ching-Perennial-Classics/dp/006...

Second Sekida's book, it's a brilliant guide, and quite light hearted as well. It's about 2/3rds practical content and instruction then some anecdotes and light philosophy.
