on a 302 what is the purpose for the tube that goes from the oil breather to the throttle body?

It's for your PCV system, to help remove unburnt gasses from teh crankcase, extend the life of your oil, control emissions, coltrol moisture, etc. If you have a supercharger or turbocharger, you are going to have to reroute that tube else you'll run into pressure problems. If you are all motor and you have a problem with that tube, you could potentially end up with a vacuum leak.
