So a couple of my friends were thinking of doing some Jello Wrestling for an upcoming party, and I've volunteered to help with some of the logistics.

I'm so ashamed to admit this to my fellow WAMmers, but I have no idea how to set it up. Which Jello do I buy, and how much do I need? Are there any considerations about using Jello from the logistic and cleanup angle?

A few of them were also mentioning whipped cream, but I remember reading on here cool whip is better because it doesn't smell as bad (once left out for too long) because it is not milk-based. Do I have that correct?

you're right about the dairy
Try Amazon.. I hear you can order 25lb bulk jello ( makes 100 gallons)

OK thanks guys. How long can cool whip stay outside at room temp and remain usuable? Does it go bad or smell bad after a while?

Cool whip.
