The first step does sound like "catalog them", and LibraryThing is a great tool for that (especially now with the expanded free access they just announced here). The LibraryThing iOS/Android app includes a bar code scanner to help.
LibraryThing's forums are also where I'd start to ask the hard questions of what to do with the collection. Especially once it is cataloged you could get a ton of good opinions in the LT forums on which books might have value where. A lot of small and niche libraries already use LibraryThing for their operations and you might be surprised who you network with once the overall collection is cataloged.
