Hence, when you increase torque output of the engine significantly you will need to move away from that design, this is where "pucks" come in. Pucks are seperate pads which are arranged in the same radius as the organic one, but because it's not one continuous surface it grabs much more quickly and allows all of the available friction surface to hold against the higher torque levels. The number of pucks is basically just a way of customizing exactly how quickly you want your friction surfaces to grab (cause friction). Also, just another bit of information, you will definitely want a "sprung" clutch design, not solid disc-- that is of course assuming you plan on ever being able to drive this car on the street.

As far as for what you want, an organic design with ceramic-copper friction surface would do just fine. You don't need a pucked design, but it would make your torque transfer during shifting a lot more agressive (it's also going to make your pedal feel a lot stiffer and shorter action).

Flywheels are cool for making cars feel more sporty, it reduces your rotational mass in your powertrain which will allow your engine to rev more quickly and you'll get better net power gains down to the wheels. Careful about how light you make it, though, too light and your engine will stall if not under load.
