Victor ESC's have an electronic brake feature, switchable on/off by a small jumper. I think most people (including me) have left it turned off as it seems to be rather a violent stop from 5+mph, and these tanks typically have enough weight and rolling resistance to stop themselves.
300-400 should be fine for your final motor drive. If by final drive you are referring to track sprocket rpm, then it might be a bit high depending on how big your track sprocket is. If you have a 4" track sprocket, that is a circumference of (rounded) 12", with a an RPM of 400 on this sprocket that is about 4.7mph The way I build is to sort out my track sprocket and the speed I want to achieve, and work back from there with motor/drive sprockets to suit. So geared motor output speed of 300-400 is in the ball park, and you can fine tune with the sprocket on your driveshaft if necessary.
