Take a look at rabbit:boot/0 - I'd also suggest having a good look at the startup scripts (such as ./scripts/rabbitmq-server) to get an idea for what environment variables will affect you. It's also worth looking at http://www.rabbitmq.com/configure.html.

Well, you can use the direct client to communicate with the broker using message passing instead of going over the wire and if the client is started in the same vm then yes, you will avoid any overhead associated with network communications.
