In that case, I'd recommend finding a buddy that knows basic car maintenance and buying them a 6-pack if you aren't somewhat mechanically-inclined in general.
Though simple, there are a few things a novice can do with a spark plug change that can result in some serious damage... Tightening too much and stripping the spark plug socket theads, tightening too little and having the plug blow out of its socket, cross-threading the spark plug, etc.
But if you are wanting to try it, here's what Arthur tried to post, short of the formatting issues...
Spark plugs: NGK is the brand; IFR6A11 or IFR5A11 is the model #. Just ask the guy at the pep boys counter. Hell just give him your car model, make and year and they'll pull up a list of compatible plugs.
As for the gap, you will need a gap tool to set it.. Search youtube for 'spark plug gap' and it should explain it pretty well.
Hand-thread the spark plug into the socket to avoid cross-threading, then use a torque wrench to torque to spec.
