There's a relevant Meetup group about 10 miles outside Memphis TN:
http://www.meetup.com/hoarders/I've really enjoyed other Meetup groups I've been a part of. They've been really good at making things happen in person, not just online.
There doesn't seem to be a hoarding/clutter Meetup group in upstate NY, but maybe you might find a local grief support group helpful in terms of holding on to "stuff". They are often available at community centers, churches, etc.
I wish you both the best of luck! (I'm not in the vicinity of either of you, but I too am trying to tackle all my junk. I know we can do it!)
