Joshua, No our book doesn't contain any material on JBoss Eclipse IDE. I've used it on a project and liked the fact that it came with the J2EE and JBoss Client JARs baked into Eclipse.
But, I still use an Ant/Maven-based build project to support testing, Continuous Integration, and push to production.
I've also used Eclipse by itself and was able to fold in the JBoss-related JARs pretty easily. I prefer straight Eclipse to JBoss Eclipse IDE because I don't want to be too tied to any one product. But it will work well for you if you decide to go that way.
