Advice for my winter project

[WhipE350]

I have a 2000 'S' with 57k miles. I'll be doing my IMS this winter (soon) and wanted advice on the clutch. I figure while in there I'll do the clutch and was going to order the 3 piece clutch kit from either Porsche or Sachs (figure they are about the same) but then it occurred to me maybe I should see what needs to be replaced before I spend the money on the kit. If the pressure plate and throw-out bearing are good should I replace them just to to make sure I have the newest revisions of the hardware or is that a waste. I don't drive more then 3000 miles a year so not like the car gets a lot of use. The clutch seems fine now.

Thanks.
