FYI, I've already ported every module from K1 to K2 and plan to release them as a mod resource. I'm just waiting on an update to MDLEdit to make that possible, due to issues that I've outlined here. I don't mean to discourage anyone else from having a go at it, but if you do you're likely to run into the same problems and you'll be repeating a lot of boring work I've already done.
Your ZIP is missing all the textures, including all the lightmaps. I've outlined how to port textures here, though I didn't cover lightmaps there because they don't have the file name conflicts that post was concerned about. If you want to get all those, you'll have to extract everything from the various lightmap BIF archives in the same manner.
That should be enough for your personal use, but for release you'd have to hunt down every texture used in the area and include them.
You'll have to be more specific about what's not working.
The models are probably in K2 already. Most K1 doors still are, from what I've seen. However, ones that aren't use may have had their lines in genericdoors.2da overwritten. To restore them you'll need to add new entries with the correct information and edit the UTD files to have their appearances point to the new entries.
