Palla,
Pro JavaFX was written for a wide range of users. The first few chapters cover the basics so you can dive in with zero knowledge of JavaFX, while the later chapters get into advanced topics like layouts, mobile, and third-party libraries that even experienced users can learn from.
We have quite a breadth of different samples in the book ranging from simple and straightforward to complex and more business oriented. I would take a look at the Pro JavaFX samples page where all the book samples are published to get a better idea:

I am not sure I completely understood you last question, but we have screenshots showing how to setup a new JavaFX project in NetBeans.
