I think that is a really good start on a list. I note Pitt, which seems like a great fit, is rolling admissions, so when the time comes you can submit that really early, and hopefully get a very early decision from them. If admitted, that can really take the pressure off the rest of the process.
Some other ideas–have you considered Rensselaer Polytechnic Institute? Troy is a decent-sized city, and then also part of the bigger Albany metro area. Very good for CS, not a terribly hard admit.
Rochester Institute of Technology is in the Rochester area, again quite strong in CS.
Finally, Delaware is yet another strong CS school, really attractive campus in Newark, a nice college town that is not far from Wilmington and in fact Philadelphia (there is an under 40 minute train, in fact).
