I am no expert, but they appear to be right to me. To turn motor on set enable high and in1 and in2 high/low depending on which direction you want to turn motor.
Edit: I believe the enable pin can be set high or low depending on which way you have the jumper connected.
You would obviously need another motor driver to power the motor if not using the l298. I think the suggestion of fusing the line would allow you to use the l298 with your motor, but would blow the fuse if you draw too much current.
