I'd like to post a couple of links if you're interested in helping.
First is a listing of great links gathered by Brian Williams at Rock Center.
Additionally, Occupy is getting out there on bikes, helping to clean up as well as feeding and clothing folks. Here is their link.
In the coming days, there will be much needed and many ways to help. Although this is going to be a hugely expensive storm in the end, there will also be non-monetary needs. We all have talents and skills that we can send their way along with our prayers, best wishes, and love.
