To preserve your playlists, you definitely need to work from within MusicBee, but copying files won't help with the playlists. Besides, I don't think copying will be necessary.
To get you started, take a look at this page: https://musicbee.fandom.com/wiki/File_Organization
You can have MusicBee reorganize your files from wherever they are now to some better-structured location. I would suggest taking it in small batches at first to see what's happening (and maybe do make copies for testing on), but once you're happy with it, it's a quick process to use Move To>Organized Folder on any unorganized files.
Removing duplicates will depend on how well-tagged your files are. The duplicates manager does a good job if the files are tagged consistently.
Thank you so much for the suggestion, I will try this as soon as I have time. As always, super helpful user on these forums!
