Buying tickets for FL...HELP PLZ!!!!

Hello all!!
I desperately need some help plz!
A friend and I are traveling from Chile to see the shows at Sunrise and Tampa. A couple of days ago I went to ticketmaster and the only tickets for Sunrise that we can buy there are all the way in the back. Im wondering if they're having pre-sales for these shows or are they actually getting sold that quickly?? :S
Also, it says presale for Tampa tickets begins this friday, do you have to be a backstage member to access the presale??
I'd appreciate any help plzzz!! =)

The tickets for Tampa are going on pre-sale tomorrow, with general sale starting Saturday. Sunrise went on pre-sale last weekend I think, the general sale starts on Saturday as well. I would wait until then when all the seats will be released.
