Sorry to see the damage, lucky that it all looks do-able, dont think you have to worry too much about the clutch.
I've a Mk2 derv, I'm on 77,000 odd, incl 3 novice days at Brands and a few runs at Santa Pod, plus some quick get aways in first, all with what you want to do. The clutch still feels OK after 2 1/2 years of giving it some stick!!! No SDi injectors though.
