Concert NYC: Paul McCartney and Ringo Starr buying tickets question.?

I seriously want to go see this concert badly. If I order 3 tickets the minute these tickets go on sale off of ticketmaster.com, will i have even a little bit of chance getting tickets? If so, I noticed the tickets can be from 79 bucks to 500. If i want 150 dollar tickets, will i get any choice? And what is the fastest way to order these tickets?
