Yes you can. We had a 3 day New York Pass and used it to go to the top of the Empire State Building just last week. We were allowed straight in past the queue and our passes weren't scanned so we could have gone back again if there had been time!
Buy the am/pm pass. Then you can see it during the day and go back and see the skyline at night. Beautiful! It is only a few dollar more than a regular pass.
No you can't. You have to buy the ticket at the building or online.
You can't go on tarace without entry pass . Pass is about$43
