Good Basic First Tune Up suggestions

[ferrariowner123]

So if you dont know, im new here and to owning a nissan pathfinder, and i just bought it about a week and half ago and im planning on selling my old RC car to get some funding so im hoping around $400 in parts money for a new tune up. Im already commited to a new deck for about $140 so realisticly its about $360

Now the dealer i bought it from had already changed the oil, thats really all they did and a replacing some sensor when it comes from nissan (hopefully by the end of the week). So the car has 100,000 miles on it and i was hoping i could some suggestions on what to do first. I've already checked the air filter, it was put it less than 9 months ago and was very clean, i was thinking spark plugs but thats were i stopped because i couldn't think of anything else, so if you please have any suggestions please list them, you guys are the experts, some of the stuff it needs right away is a new corner light (but im gonna fix it with some new smoke light covers) it doesnt have a key FOB or wireless entry thing, thats $60 new but thats gonna be a christmas present, uh a new antenna, the little licence plate cover that says pathfinder broke off, but im gonna get that from a wreck hopefully, uh yeah i need either a new bulb or new fog light. Car was in a very small fender bender, probably from silding in snow or a car slided into it, either way its gonna be and easy fix.

Oh and its a 1996 Nissan Pathfinder SE with 100k as i said, manual, off road package,

So again thanks for reading my riduliously long piost

Sincerely

Ferrari

check all fluids oh and welcome by the way, change the ones that need to be change, major ones, trans,transfer, diifs, brakes, coolant, check all hoses and belts, look for leaks below water pump housing, spark plugs, sparks wires, distributor cap and rotor, gas filter and so forth, pcv valve just check or have someone check for u and then make a list of order of importance

Would you recommend changing the brake fluid as well? I guess it depends when and if was ever chandged before, what interval would you recommend for brake fluid?
