That is model # of your upper unit. The controls you have at the ceiling will determine what you can or can't do. Most come with a connector to add heat strip/coil to them. They will help take the bite out of the air a bit, but I certainly would not count on that to heat it up too much when it's cold. Go to ( www.dometicusa.com ) and match your control unit to possible accessories.
No. You would have to replace the entire unit. There are quite a few differences, including the circuit boards and thermostat, unless the thermostat is already digital.
