The factory Trailer Towing Package
always includes an external connector permanently mounted just below the bumper. Class I and II packages would have a 4 pin connector while Class III (5,000 lbs) would have 7 pin connector.
Class III packages have the extra wiring under the dash for an electric brake controller.

Do I need to add a tranny cooler? Is this vehicle already set up for "Light' towing..?

Without looking directly at the thing your sales person called a transmission cooler, I would say "Yes, you need an auxiliary transmission cooler". (A picture is worth a thousand words.)
Depending on your climate, that heavy duty radiator may not be a bad idea either.
