You do need to supply 12 volts to the motor controller for it to have power. The power is isolated from the raspberry.
You can add /dev/ttyAMA0 to ~/.pypilot/serial_ports or it should be possible to add using the openplotter-pypilot gui.
You have:
failed to open servo on: ('/dev/ttyAMA0', 38400) [Errno 16] could not open port /dev/ttyAMA0: [Errno 16] Device or resource busy: '/dev/ttyAMA0'
Maybe you are running bluetooth services which are trying to use /dev/ttyAMA0 ? I would find out why the device is busy.
