Does anyone know if a list of the data files that need to be imported and the sequence of their imports? For example, I want to import items, what are the files (tables) they need to be imported to and sequence. I am looking for all modules for D365.
You don't need and shouldn't import individual tables. Use data entities instead.
You still may need several entities in a certain order and then you should look at data packages in LCS asset library. For your example you might need the one called Template-8.0-310-Product information management.
