If I understand your description, I then have to divide the voltage (4.5) by the Ohms (12.4), which gives me a value of 0.362.

Yes, that's correct, 0.362 Amps or 362 mA (362 milliamps)
From that we can now say that the 12 Ohm resistor is ok and that the power it's dissipating approx. 1.63 Watts (the current multiplied by the voltage) is ok for it's rated wattage (3 Watts in the parts list in the manual)
