You don't need couches or TVs in your gameroom.
The location of the door is pretty important, particularly when it comes to optimal location of cockpit cabinets (and pins if you get any of them), draw the room with the door in paint or something so we know what you are dealing with.
Also, Star Wars cockpit will run you close to $3000, while you can probably get a nice upright for $1000. If money is any issue than I suggest getting the Star Wars as an upright and grabbing a Sega Turbo cockpit instead (similar to Pole Position, way more reliable than Pole Position, usually goes for $200-$400).
