you are lucky son!!! passenger side is the easy one to remove. if its a first gen remove the air intake tube and take the valve cover off, if its a 97-98 take the intake tube off and the throttle body, then remove the valve cover. i dont think you'll be able to buy one side, they come in a pair, autozone carries them, you need a valve cover set with plug tower oil seals, i get fel-pro's cost about 70 bucks for the complete set. the valve cover gasket is like a rubber ribbon gasket, and under the valve cover, where the 4 plug holes come through the valve cover are 4 oil seals that stops the engine oil from leaking into the spark plug journals, not a catastophe but can wreck your coil pack boots and cause spark arc if not fixed. pass side isnt bad to do though just be patient.
