re: I see that people can edit their own profile info if they are set up as WP users

Yes, you’ll need the Link extension and you might want the Form extension too.

re: is it possible to “split” a listing so that the user can edit part (like their profile info) and the admin only can access other aspects of the listing (like categories, search terms etc?

Not out of the box but I suppose it might be possible to have something custom coded to make this possible.

re: is a click to listing from a google map possible?

Sorry, no, not at this time.

Hope that answers your questions thoroughly!
