Came across this once before on a civic, the heat shield eats through the second O2 sensor, shorting the heater circuit, and blowing the ALT/SP SENSOR fuse, so that the alternator and speedo never work. You'll need to see if it shorted, and if so, what fuse it blew, they are probably related to some degree if they all occurred at the same time.

It is indeed just a blown fuse from the o2 sensor wire shorting to the metal. Repair/replace the o2 sensor wiring and change the fuse and your problem will be solved. Your alternator and transmission sensor is fine and does not need to be replaced.
