Kev,
problem you have is thus (I think)
to answer your question first, the clutch you have should be fine, its quite new and would work OK, but really in this application Caterham would specifiy there AP clutch and Cover (cost a coupla hundred quid), but thats not your real problem anyway. Flywheel is your problem!
to mate your VVC to gearbox you will need a Rover 1.6 K series flywheel (rover VVC will not fit bellhousing), and a Ford based clutch (to fit the gearbox splines)
Essentially the VVC flywheel and clutch you have are scrap.
Now if you are using your VVC ECU then it must be a 1.6 flywheel (from Caterham or their lightweight one at £250 is nice). These flywheels have the correct trigger pattern for the crank position sensor info to ECU.
Alternatively you could use you lightweight 1.4 flywheel but you'd need to run a programmeable ECU that can recognise the 1.4 flywheel trigger pattern. Emerald should do this but ISTR Emerald still cannot be used on VVC.
Now if you'd bought a boggo 1.8 things would be different
