Good info all around.

No, just the opposite, any power used to spin the rotating assembly will be lost to the ground. So decreasing the weight does not decrease usable torque it will actual increase how fast the power is available. Think of it just like a lighten flywheel.

If you are just replacing the E-shaft than no as they are prebalanced. I like to error on the safe side and would still have it balanced.
