Man that panel looks scary. ground bar is on the left with all the bare copper wires going to it. Neutral is on the right with all of the white colored wires going to it. I would need to see the power requirements for everything that you want to put on the circuit to determine the load, can't say 100% until I know what is on the circuit. If it is just the stove and the lighting you should be alright, but like I said I would need to know what is being powered on that circuit. If you have a meter that would be the easiest way to determine the amps being pulled on any one breaker, it will give you a snapshot of how much of your breakers capacity is being used. I recommend hiring an electrician
