Questions about the 190 NJ Transit Bus?

I usually take the 320 bus to park plaza but since I have to get there at around 6:30am, I'm planning to take the 190. I looked up the stop on google map because the map on the njtransit site kinda confused me. The stop is says that goes closest to Plaza Dr. is Paterson Plank Rd. & Rt. 3 Entry Ramp on google, does anyone know how accurate google might be? Also about buying the ticket from the vending machine, I'm gonna catch the bus from the Port authority bus terminal, the machine asks for zone and so on, what exactly do I put in to ride the 190 bus to Secaucus?
