go with the larger alternator if you plan to add more power later.

if the radio is on but at 0 volume, yes the amplifiers will still draw some current due to the bias voltage of the transistors in the amplifier circuitry.
This holds true essentially for any class amplifier. The current draw won't be a large amount, but amps even with no input signal still draw power and produce heat.
