You are looking for technical answers to problems that are type, and can also be operator, specific.
The MCC is not a technical course (although conducted properly you will learn masses about the operation of a multi crew aircraft) but is designed to give you an understanding of how the flightdeck, and the cabin crew and all other resources available, work together.
Find out what sim you are going to do your MCC on, and learn the basics of that, but don't go too far, or you will actually cause yourself more problems. I did mine on the B757, and before hand I got hold of the MCC manuals from the provider, a Microsoft Flight Sim B757 add on, and also bought the ITVV flight deck DVD's of the B757. All of these gave me a good knowledge of the flight deck, and demonstrated enthusiasm and learning ability.
If you want to prep properly for what the MCC is truly about, then the best book you can read is called "The Naked Pilot: The Human Factors in Aircraft Accidents" by David Beattie. This book really exams the issues in operating a multi crew aircraft, and covers most of why the CAA felt that the MCC course needed to be brought in.
Remember, the MCC is a non-technical course. But treat it as another serious module in your flight training, and the sim time as interview prep, and you'll come away with a good insight of how it really works. Many people treat the MCC as a "tick box" course that you can't fail - that it is a very poor way to complete the last main module of your training, and get your first real taste of what line flying is really like.
Superpilot - I don't for one minute think this is what you are doing, as you are pro-actively seeking help ahead of the course - good luck with everything!
Out of interest, where are doing your MCC?
