Either way I don't harbor any bad feelings towards the guy and I hope the South Park guys don't do anything to extreme (though they probably will).

Like Sean said, I would not be surprised if the next episode of South Park is a tribute to him. The episode that ripped on Hayes by having chef be part of a cult that brain washes its members into becoming pedophiles ended with the note of "even though chef got brain washed into becoming a creepy pedophile, let's remember the good times we had with him." Also at the end of the episode chef redeems himself by over coming his brainwashedness and sacrifices himself to save the kids, only to be resurrected by the cult in a parody of ROTS birth of Darth Vader scene.

All this to say, I don't think Trey Parker and Matt Stone hold any real hard feelings towards Hayes, especially with the episode ending with a hint of sadness at how things turned out and Stan's speech about not blaming chef, but the cult that brainwashed him. They did rip on him pretty hard, but that was when he was still alive. Now that he is dead I am sure they will treat him with respect. If they make any statement about it at all, it will be one that puts Isaac in a positive light.
