Exactly. Don't worry about any gaskets until they are needed. When I get a new used car there are always things I do...

1) A good tune-up
Oil/filter change
Spark plugs (I always use the plugs the manufacturer specifies. I have tried fancy plugs without any benefits)
Wires (if necessary)
Air filter
Fuel filter

Tranny fluid/filter change

I don't use additives for fuel or tranny, I don't believe they help.
