DR elmore - One more possible suggestion/solution...
Since you do have a date that you know you want to fly out, and I'm guessing a time frame is not that big an issue... And I also don't think you're worrying about accumulating frequent flyer miles/point at this time...
I would try to see what kind of prices come up on those last-minute deals sites like Hotwire.com, etc...
If you get a good deal, then take it. You may not know the airline nor the time of day you're flying.
Then cancel your existing reservation on USAir - or United - I've lost track. Yes, you will be penalized anywhere from $75-100, but all the major airlines do that now. You may end up getting out of NYC and to Ohio for well under $496. And also sooner rather than later.
