Launching 5speeds accords hard will wear your throughout bearing and pressureplate. My accords plate is showing signs of wear when it is really hot out. It starts to speak, this means you have been doing lots of hard shifts the springs and fingers are showing signs of wear. The pilot(through out bearing) can be covered under warranty the pressure plate and clutch disc are not. As for the rough idle--you must have really whaled on the car. I run synthetic oil since day one and no amount of romping has phased my engine yet. Still churps from 1-2 as hard as ever.
