Fuel filter isn't harder than any other car really. It's back near the right rear tire. Jack the car up a few inches and look up. There it is. Pull the fuse for the fuel pump, start car, let it die. Take off filter, install new one (check the box before you leave the store to make sure you have new clips). Shouldn't take more than 20 minutes.
Never done the PCV valve. Try it out and let us know how hard it is.
