Can u go into rhe station and buy a ticket still.

Yes you can

Yes

If you buy your ticket online be prepared to print it yourself cuz you must have a printed ticket to ride the bus and they will NOT print one for you at the station. Pro Tip: cheaper online a few days before your trip.

Yes you can must have id if your buying with a agent vs kiosk no id

Yes you can but is better if you buy ticket online or by phone
