If you do not want to mess around with teenagers and broke down cars then I would hang everything but the knock sensor. If the pressure regulator or the engine speed sensor take a dump on the road usually no amount of pounding on them is going to get you home. Make sure you replace the correct suppression relay as certain year models run a pair of them and one will leave you stranded and the other will make it so the auxillary fan does not come on. Just pull the relay while the car is running and if it keeps running well then it must be the one on the other fender. The only thing that comes to mind that is not on your list is the power stage.
