In addition to the textbooks listed by planetmike, my college SM class used one called "The Art and Craft of Stage Management" by Doris Schneider. It didn't have as many form/paperwork samples, but it was collectively our favorite in terms of the usefulness of the information.
Another book that's great for any person in theatre is "Backwards and Forwards" by David Ball. AMAZING insight. You will never read a play the same way again.
