The s-pipe is the piece between your header and catback that contains your second cat. I believe most s-pipes remove the second cat.
A resonator is used to combat rasp from your exhaust. Basically, when you remove your cats, the high frequency soundwaves from the combustion in your engine aren't absorbed by the catalyst material, and are free to bounce around like crazy in your exhaust, which causes rasp. A resonator is used to absorb some of those bad soundwaves to eliminate rasp and even out your exhaust tone.
As for the anti fouler, you don't need a spacer. The anti fouler itself is a spacer between your O2 sensor and exhaust gas that fools your car into thinking you have a cat still in there. I have a cheap ebay one and it works sometimes, but I noticed it's dependent on the octane rating of the gas I put in my car.
