Best practices/approaches to custom instrumentation of applications

Is there any documentation/FAQ/readmes available on writing custom PBDs and/or best practices in custom configuration/instrumentation?

When you come in with Wily to an application that's having performance issues - where do you start? Obviously you deploy the agent and look at metrics that get picked up out of the box, but then you probably get to the point where some things are not showing and I'm guessing that when you'd start writing custom PBDs... Where do you start? What do you look for? Work with development to identify key classes to be instrumented? YATT their code yourself? Start broad and then narrow things down?

Is there a doc describing PBD syntax? General practices of writing custom PBDs?

Sorry, total newbie here, I've been using Introscope for many years, but as a user (CA engineer setup all instrumentation). Now I'm looking to expand the use of this tool to other apps and trying to figure out where to begin. Any guidance is greatly appreciated!
