I haven't done the C14 but have done a couple of other bikes. Usually it's a piece of cake. You didn't mention buying a new gasket. That will be required unless they use an o-ring. The last bike I did, removing the stuck on gasket was the hardest part of the job. Why do you need to buy new springs? Unless it was really, really overheated the old ones should be fine.
I watched a race mechanic replace the clutch on a superbike at Road America. 5 minutes. Of course he had everything right there and nothing was stuck together.
Finally, soak the clutch friction plates in oil over night before installing them.
