the three demo capx in the first post do give a really good start. I started with nearly no experience and got a good game up already (demo link in a previous post, which shows an early stage).
Best way to learn this plugin is by working with it. Set up a basic layout (only one object), put an texture on it, move it around.
You will learn the basics easily.
For the Tank, I can even tell you without seeing the code. A lot of logic is involved in this. the tank is made up by several objects and each object is moved on his own (wheels = rotation).
Good luck
