this one for Google Drive and Docs that is geared toward teachers, I haven't written one from a deployment perspective. Fortunately, I don't have to write that one because Google already has.
Google's K12 Guide to Going Google contains six very detailed sections on deployment of Google Apps for Edu. The guide covers technical integration, outreach, professional development, promotion, launch, and staying up to date. There are step-by-step plans outlined in the technical integration, outreach, and professional development sections. The promotion and launch sections provide templates for your use. The staying up to date section refers administrators to the new Google Apps What's New? site.

If your school is going Google, the K12 Guide to Going Google is obviously a great resource. But if your school is still gathering information before making a decision about whether or not to "go Google," the K12 Guide to Going Google will give you a good sense of what the process entails.
