it looks like you've possibly got a couple of probs there, but here are a few thoughts:
Red light means ignition is on. Without this bike shouldn't run. Clocks are on same fuse so no clocks backs up no light on ignition.
Red Light should go out once bike started not come on.
Won't start or run with choke pulled out sounds like a possible carb/jetting issue, but its not that cold so choke may not be needed. Would say thats a side problem to fix after the electrical one. As to cutting out, would say that is related to the electrical problem.
I would suggest looking for damaged wiring/shorts on the side it was dropped on. Get it so the ignition light comes on when it should then go from there. Check if the igntion fuse (under seat) has blown, if it has it may explain why no ignition light/computer when there should be, also if blown due to a short may explain why it comes on when running. Also well worth checking the actual ignition switch has not been damaged in the drop as a short in that could cause these symptoms by acting as a 'kill switch'.
If totally stuffed, disconnect wiring harness and run new wires to ignition so you know where you are at.
Its a wiring problem primarily not a carb problem, carbs don't make lights/computer do wrong things, nor make bike dead cut when revved. Do the wiring then do the carb (if needed).
It will prob be a proper trial and error job, but getting the ignition sorted is the key.
