The bulbs blew (surface lighting) and tripped the circuit breaker. When I replaced the bulbs, the surface lighting and the vent don't work (although rest of microwave is fine). Is there a fuse or something that I could replace? I unscrewed the bottom of the microwave but looked like I would have to take more apart to find out if a fuse even exists.

when that happens there is a trace on the circuit board that burns, I just resolder the missing trace with a piece of wire, but if that is not something you can do, you will need a new circuit board. To get to the circuit board, remove 2 screws on top above the vent grille, take grille off, remove 1 screw above the control panel, and take the control panel down..Make sure your microwave is unplugged. Now you can remove the 3 or 4 screws that hold the circuit board onto the panel. Look at the bottom of the board, and you will see the bad trace.

So is this something a novice could do? And if yes, where do I get the part? Thank you!

A novice can do it, if you can solder, you can fix it for free, if you would rather get a new board, you can get it here. AP2631621
