I’ve found these to be helpful in porting a ZF1 app to ZF2, which is in Beta1 status at the moment. Rob Allen’s tutorial -updated for the beta, worked for me out of the box using git submodule. The programmers reference manual for groking new concepts, although sometimes it takes a couple of reads. Finally, looking at the code for the EdpUser module helped me figure out how to use DI and how to structure a functional module.
Once you start to understand the Dependency Injection container and the new Module bootstrap, in many ways its easier to get up and running than with ZF1. I love that modules are first class citizens in the new MVC implementation.
