Street parking. Public transportation is nearby in buses and subway lines to 14th Street/Union Square.
If you arrive before doors and speak to security, usually they will let you jump the line.
The main way to get to the show floor is via a flight of stairs. In my experience, there is one elevator, and it's a freight elevator - you need a member of staff to bring you back to it and to operate it.
There is no designated accessible seating area. On the main show floor there is a side platform with seats which is usually reserved for VIP ticket holders (I think there are only stairs to this area).
There is a balcony that can be mainly be accessed by stairs, or by the freight elevator. Half of it is closed off for VIP/guest listers, and they have seats and tables. Sometimes the venue will bring you in early and give you a folding chair next to the sound desk in the balcony, and from there the view is great, but there's nothing blocking you from other fans. The rest of the balcony has no seats, except for a small lounge in the back with couches by a bar - from the lounge, you can't see the stage but the show is broadcasted on TVs.

"I once went to a show here when the entire balcony was closed off, and I was given a barstool on the main floor. However, they put the barstool up against the back wall, next to the bar, so I couldn't really see and everyone was at the bar talking so I couldn't really hear the show either. They would not let me move the barstool closer."
The only restrooms are on the first floor, next to the coat check / box office.
