Pretty much what you said with the exception of water as CF has its own water. Learn about grass textures, billboards, what unity packages are and general navigation, moving objects etc.
Mike has issued a starter course with most things already set up. Along with the tutorials he's also done, people are catching on very quickly. It's when you wish to start creating your own textures, trees and course objects or use real terrain data,... that more learning is really needed. I suggest getting confidence avoiding such for your first course and learn specifics on the fly rather than extensively learning Unity and other concepts in computer graphics up front.
