There is no such thing as a spark plug gasket. You have oil intrusion in the cylinder. This can be caused by poor ring seal or oil in the intake from the PCV system. If the engine has good compression on all cylinders it's most likely coming from the PCV.

If you are asking how hard it is to changed a piston ring, it's too hard. It requires pulling the heads, bottom end, pulling the piston out of the bore then replacing the ring and re-installing. I doubt you could do it with the motor in the car, so you are looking at pulling the motor as well.

Your friend is an idiot, spark plug gasket lol. You should have been more descriptive with the whole oil on spark plug thing. Oil on the outside of a spark plug is hardly worth mentioning, get new valve cover gaskets. Oil on the electrode is a big deal like everyone assumed you were talking about but lucky for you isn't the case.
