ok plan so far:

-Arduino Uno
-VNH5019 Motor Driver Carrier
-HC-06 bluetooth module

  • Brushed 24V 58W DC motor
    -(large battery with 24 V)
    -(small batteries with 5v + battery holder for arduino?)

A bluetooth module could be this one: Bluefruit EZ-Link Shield - Bluetooth Arduino Serial & Programmer [v1.3] : ID 1628 : Adafruit Industries, Unique & fun DIY electronics and kits

Your module is significantly more expensive and looks different. what is the actual difference?
