Grrr, forum just lost my reply! Here it is again;
I think you might do well to throw out the Quick Start Guide. It is draft, incomplete and inaccurate in many respects so it's actually worse than no documentation. I wish it would be updated or pulled.
I bought the USD $10 Admin and Devel Guide for 3.x. It is much better, I was actually able confirm my installation and run the test suite against it. It lacks a sample/template project and a chapter giving the quick overview of Jboss, but you can download sample projects from the sourceforge site for jboss that work.
Also, there seems to be a bit of 3rd party jboss documentation, check for instance http://sammaher.com/jboss/ which I just saw on this forum.
Good luck, things are going fine for me now that I pitched out that old Quick Start!
