i also get an unbelievable amount of noise when the motors are running.. with both going full speed, i cant even make out the picture on my tv. i think i may need to add some caps to the motors..

Cap's across the motor may help, but it's probably the result of the frequency of your PWM. What is the freq anyways? Maybe we can help you come up with something a bit higher so you can't hear it (but your dog will go nuts!!!).
