Yes, you should. Unless the Valve cover is vented. Then the vent tube
should run into a collector of some sort to keep oil from spraying all over
your engine and compartment, as has been my expereince.

I don't know--I have a Weber.

Yes--you should use pre-smog specs to set your timing.

An option. My 1500 has always run so cool (except once) that I had to go
with a 190 degree thermostat. So I have never thought much about an oil
cooler. Sounds like you probably don't need one if you mean by "in good
order" that your engine is running cool.
