Andrew Devis has 2 more tutorials, this time on some AE camera basics:

“Cameras are notoriously difficult to get to grips with in After Effects. In this tutorial, Andrew Devis explains some of the behaviors and problems that are common to camera animation and then shows how … to create a simple camera rig, and why it is important to get the order of the layers correct to achieve predictable results.”
