Can I use Supervent double wall stovepipe from the stove to the Duravent chimney? The stovepipe will be this, plus maybe another 24" section. (Is an adaptor needed between the pipe and the 30-NC stove?)

That should work. The double wall should drop right into the stove. You will need an adapter to go from the stove pipe the chimney...if the kit doesn't already have one. Have you considered adjustable stovepipe? Makes cleaning easier...unless you are gonna just pull the stove baffle out to clean...
I clean the vertical pipe above my NC30 without removing the pipe. The baffle is very easy to remove and the large firebox makes the use of a sooteater very easy for bottom up cleaning.
