Vienna isn't hard to work with once you get a handle on the relationship between samples, instruments, and presets. In your case, you just have to import each element of the ns_kit, which are already available as individual soundfonts. Is that the version you have? It has a snarepack, cymbalpack, hi hat, etc? I think it's version 6. When you get ready to assemble the big soundfont, I might be able to help you if you run into any snags. That's about all I've done for the last three months is make drum soundfonts in Vienna. It's hard to find individual samples that actually sound like they go together, so if you come across something like the ns kit, you wanna grab onto that! I don't really care for version 6. I think version 4 was his best. Version 6 has wierd kicks, and the snares are real thin and high-pitched. Not good for me, but may be great for others. Anyway, good luck!
