Do you need 3-wire romex to feed bedroom ceiling box by electrical code?

No, you can feed it with a 2 wire Romex + ground. It depends on what is mounted on the ceiling. If it is just a light all you need is 2 wire + ground Romex. However if it is a fan/light and you want to control each one independant of the other you will need to use 3 wire Romex + ground. This is of course if you have 2 seperate switches. You would then connect the red wire to the blue light wire and the black wire to the black fan wire. If you use 2 wire Romex just connect the blue and black fan/light wire to the black wire in the ceiling box.

Can you run Romex through a wire mold?

The key is that you don't want to cause over-heating in wire. The answer is you can probably do what you want unless it involves high current and a small cross section in wire mold such that the Romex could generate too much heat. You could always strip out the wires inside the Romex and just run them in the wire mold.
