First question has been answered correctly. If you go to Oracle's website and find the exam objectives they are a close match to what's in K & B 7. FX is not in the objectives, it's not in the book.
As far as advanced Java, we have
Servlets,
EJB (out of date), and Design
Patterns.
We discuss other advanced Java topics, and we always welcome authors who might want to try to write a Head First book. For example, over the years many people have asked for some variation on "Head First Spring and/or Hibernate". I don't think that our publisher O'Reilly ever got a single author who expressed interest in writing that book.
Right now Kathy and I are wrapping our brains around functional programming in general, and Java 8 - that's going to keep us busy for a while
