Tune up question

It has been over a decade since my 72 sel 4.5 has had a tune up. I am going to change the plugs, wires, and fuel filter. Do I need to change the distributor cap and ring as well? Is there anything else that needs attention? I am trying to get better gas mileage. Any help would be greatly appreciated, thanks.

Cap, rotor, wires, points, plugs, air filter, fuel filter would be pretty thorough, parts-wise. After 10 years, I'd say it's due.

Can the distributor and points cause a decrease in gas mileage? The car starts up and runs fine.
