I think the jboss.xml file is described in the free Quick Start guide. You can read the DTDs for these files in the docs/dtd directory of the JBoss distribution, or you can buy the JBoss and JBossCMP documentation at FlashLine.

Java Authentication and Authorization Service. We use it to validate user credentials and to get credentials for databases (JCA).

This doesn't sound like a good design, but since is sounds like you will be writing raw JDBC you can open any datasource you like.

Don't know on this one. Not my area.
