If I'm not mistaken, the pressure plate should come as part of the clutch kit. A good kit at least. Don't flame me if I'm wrong. Yes... you want to do as much in the clutch area now, while it's all ripped apart otherwise you'll just rip it apart again in 10K to do that too. I've learned the hard lesson of spend a bit more now and save a lot later. Hopefully that was of some help.
