oil-3k if dino, filter as well
fuel filter-2 years, at every tuneup
plugs/wires/cap/rotor-2 years, and check the base timing setting
transmission-30k
rear axle fluid-100k
brake fluid-2 years, more if you race it
radiator flush-2 years, replace cap at same time
PS fluid-couple years, maybe longer if its not turned black
you'll probably end up replacing the battery once every 5 years or so
I never replace the PCV, but I do check that its still working.
basically it comes down 'everything all the time'
