Hi.
Nothing about Flight Simulators, but... since you will start flight training, I would recommend reading
William Kershner?s books.
They're well illustrated and discuss every aspect of flight instruction in detail, including most common mistakes and so on.
They're a great help. Since there are 3 other guys with you, maybe each one buys a different book and then you swap.
Also a great help is doing some "cockpit hours". If you can, go to the airport and spend some time, sitting in the cockpit, doing checklists and memorizing the location of instruments switches, and so on. Don?t bother if people think you're crazy.(we know you are...

)
My first flight instructor told me to buy a "plastic mother", so when he yelled at me calling me names, I?d know he was referring to that "plastic mother", not my real one, and take no offense...

Buy yourself one too.
Good luck!
