I assume you used the rainbow program you found to get this information. Skimming it over everything looks fine (also if you didn't realize hit_pack_xx.pac matches tex_pack_xx.nut. So texture files, collision files, and probably model files are linked by their number in the filename).

Admittedly there are a lot of texture files still without a description (including the ns_logosx.nut files). While I'm not even 100% what the difference is between some of them are, as some seem nearly identical, if you also want to give them descriptions now would be a good time.
