When replacing the clutch, what else do you need to do?

Should the pressure plate be replaced too?
Does the Flywheel have to resurfaced?

Anything else?

Thanks!

I always resurface the flywheel,replace throwout bearing,pilot bearing and trans input shaft seal (they always start to leak after) I only replace pressure plate if it has problems but it's better to put in a clutch kit.(disk,pressure plate and release bearing) I don't because I use a tilton setup and it's too pricey.but for stock I would just so I don't have to look at it till I need to replace it .
