When changing the spark plugs and plug wires, would it be more beneficial to change the ignition-control module as well?

If it ain't broke, don't fix it.
The question is, does it cool correctly now? If so, I wouldn't screw with it... my '97 only gets up to temperature if the outside temperature is above 50F (kinda annoying when you want the heater to work), I have my OBD II dongle thing in with Torque hooked up and when it's cold the needle is down by the C and Torque is saying I think 72C which I think is 165F. I even put in a new Motorcraft thermostat, no change. It looks like someone changed the thermostat housing which if it was too long could bypass too much coolant with the goofy design... Unless my fan clutch is stuck on, I can't imagine the heater core taking that much heat rejection...
fair enough, maybe I'm just too used to the turbo and some self imposed issues with a tiny fan and a 2" thick radiator with no effective fan shroud. Having heat in the winter would be nice though... no mater what the heat in my '90 is amazing, if the heater core wasn't so buried in a '97 I'd just change it, it does put out heat once it warms up though but by then I don't need heat...
Egr valve can just be cleaned. No reason to replace it if its functional as it's not a "wear item" like spark plugs. O2 sensors would depend on mileage. They do wear out but last quite a long time (100,000+ miles). Coil/pack is also is not a wear item, if its not broken there's no use replacing it.
