Freecycle, Habitat or Goodwill if they take those kind of donations (some don't), or sell it all to an architectural salvage firm. I think selling it all piece by piece through Craigslist would probably be overwhelming to someone with those kind of issues ... being a little borderline there myself, I know I wouldn't be able to deal with something like that through CL.

Much better IMO to get rid of it all at once if possible - a lot of charities will send a truck and a couple of workers to pick it up, and I would expect the same for architectural salvage places - or give it away on Freecycle.
