An email is being sent from Apple to education customers this morning, offering a free white paper on Mac management. Entitled "Solutions for Systems Management," the paper can be accessed by entering your school's name and zip code on a special web page.
It includes solid, basic information on assessment of your school's needs, deployment of a solution and even a solution's typical lifespan. Apple products are featured, of course, like Apple Remote Desktop and Mac OS X Server, but the paper also describes some third-party products like Deep Freeze and K2 Key Auditor and Key Server.
It's certainly not the definitive paper on being a Mac-friendly administrator, but a decent reference. You can find out more about deploying Mac OS X in education contexts from the indispensable Macenterprise and AFP548 sites.
