Thanks Gigantor. Even if it is a little big, it won't be the end of the world. It's not like I can't buy another frame a while down the road.

In my last post I neglected to mention that I just picked up an old Raleigh 10 speed that is a 55cm, and it is pretty uncomfortable. It obviously has a much more relaxed geometry, but I literally have to raise the seatpost as high as it will go for it to be bearable.

No it is still being shipped. That's why I decided to get some input from here, if it was a catastrophic decision and I should have gotten a 53 or a 50, I could easily return it.
