Also, would attaching a heatsink to the motor do anything? I've read somewhere that all it does is trap heat between the motor and the heatsink!?
Forget about what you read. Aluminium has a low heat capacity. That means that it will absorb heat much faster than other common metals. This will draw heat off the motor, and the heatsink will get hot. This redistribution of heat reduces the motors temperature. The end result, is long run times and less comm-brush damage. Also, you can freeze the heatsink before the race. Heat always flows from hot metals to cold metals. So the motors heat will flow to the heatsink much faster.
