Kathy,
I had four folders of paperwork for my tribunal. That seems to be the norm. I had the impression that the judge and the doctor both knew about my case, and the Doctor asked my questions that led me to believe he had looked at the LCWA report, so I was able to tell him about aspects of it that I disagreed with. I had written to them using the B&W guides, and told them about various events with the DWP, as well as what I thought the outcome of my claim should have been. I felt a bit cheeky doing that, but they never mentioned it. My overall impression was that they knew all the details of the case before I got there. The legal man was really nice. They'll do all the talking at the outset, so you just listen, and don't give them any information they can use against you. Good luck!
