Depends on the type of vehicle you are driving, road conditions, driver reaction time, etc. The average car will take 121 feet to stop after the brakes are applied. Factor in reaction time and the car will travel 265 feet before it stops.
You should be 2-3 seconds behind a given point that the vehicle in front just passed. At 65 mph, that is 95 feet per second, so multiply by 2 or 3 and you should be 190-280 feet behind

about 220 feet
300 feet
It perfectly depends on where you live or drive. You should dim your headlights right when you see another vehicle in front of you or right when you see the lights of another vehicle. It doesn't matter if you are seeing the tail lamp (both of you are traveling in the same direction), you should dim the lights or else it is going to make difficulties for the driver in front.
