Spark plugs: gap to 0.032", do not use platinum plugs, they do not run well in these era of engines... go with Bosch or NGK non-resistor plugs
As far as cap, rotor and wires, I would go ahead and do them due to the age of these parts. ceramic becomes brittle, wires start to arc, etc. However, if you replace these parts and it makes no difference in performance or economy, just keep them as spares or put the old ones back on and keep the new parts as spares.
I think the 300E/300CE tank capacity is 18.5 gallons,
so 300 miles / 18.5 gal = 16.21 MPG with an actual figure a bit higher since you are not completely draining the tank every time... seems a bit low, most people seem to get about 20 to 25 MPG with their cars...

The most I have ever filled up to in the last 3 years is 16 gallons. Even after driving on the light for 30 odd miles..
Before I moved here to AZ and use A/C all the time, I averaged 20mpg 400mi on a tank. I unfortunately only get 15-16mpg now
As stated above, being proactive, especially if you think they are original might be a good idea. You may even find your fuel economy and power will improve. Stick with OE items and you will save yourself time and money in the future.
Definitely look at the idle control valve vacuum hoses. If they are rock hard, replace them!
