slipstick:
The OP is not using PWM/analogWrite() and the motor driving sketch doesn't include the servo library anyway.So could you perhaps be a little clearer about what we are expected to discover in the Servo ref, 2nd para, cus I can't see it either?

I assumed that at some point, the OP is going to want to control the speed of the motors, and is going to hit a big wall of disappointment.
