Was searching the web to see if there was a quick way to find out what runways were active at EWR and stumbled onto this:

Seems accurate for KEWR, not sure about JFK, LGA & PHL. Lots of other usefull links on this site. One thats cool is the arrivals and departure flows for area airports:

Select the airport and runway and watch it go. I found it useful to figure out were the traffic is going to/from in my neck of the woods.
