The metadata for the NJ MOD4 (tax parcel) database states that you may download the data and use the it to make maps, but cannot re-distribute the raw dataset (I have been looking into this recently). I think it's ok to take and post screenshots, but I ain't no lawyer, so caveat emptor. 
As I mentioned in another unrelated thread, I have recently figured out how to associate the tax data with parcel shapefiles and create my own maps like the ones on the tax search site.
I have roughly thrown this together into Garmin's format so that it can be used on a handheld GPS (or on your computer with Garmin's free software), but need to do a bit more work on it. I will start a separate thread to discuss this soon, and make a sample map available for beta testing.
