That area is all just sleepy suburban towns. Very nice and quite, but not necessarily urban. I think your best option for something urban is New Brunswick. You'll have a city environment (with JNJ headquarters I should note) and large college population. This is close driving to Raritan and also ideally located on the North East Corridor train line to take direct to Manhattan. The ideal urban location for you is Hoboken and Jersey City but commuting from there to Raritan is soul crushing.
