There is nothing wrong with attaching the second wire to the existing circuit breaker. It will still work fine.
Yes you do have to be careful about the number of circuit breakers allowed in a 30 amp distribution panel. In mine, there are a total of 4 breakers, all connected to the same main bussbar. The 30 amp main is a minitwin breaker with a 20 amp, and there is another mini-twin breaker with a 20 and 15 amp breaker. That is pretty normal for a 30 amp panel.
I would first mark the circuit breakers, so that you know what one is feeding the A/C and microwave, and other circuits, before deciding on what one you will put both wires on. If your primary reason for running the new receptacle is to plug in a heater, then the one marked A/C would be a excellent pick, as you will not be plugging in the heater and running the A/C at the same time. Yet if you wanted to use the new receptacle to run an electric fry pan, and also would normally be running the A/C in the summer, you would have to decide which to run, as you could not run both on less than 20 amps. So putting it on the same breaker as the TV sets, and not the microwave might work out better?
