I'd also recommend a Stage Management textbook to keep around. The pamphlet is a great idea for an "at-a-glance" type document. As KC said this place is a great resource, and there are also tons of posts regarding stage management texts. I think most are relatively inexpensive, too. A copy of the "backstage handbook" may also be beneficial - a text meant more for technicians, though I've found it invaluable to have in my kit.
