Gearing and Tires

Currently have a 2007 unlimited with 2" body and 2" suspension lift running 315s. Looking to go to the new 2013 unlimited because of the difference in motors. The 3.8 lacks a great deal of power to make it pleasurable to drive. I am told the only was to get 4.10 now is a Rubicon. The Saharas can go to 3.73. Is this enough to run 315s with a 5 speed auto now and 85 or so more hp?

Looking to go with a 4" suspension lift this time, some say you have to replace the drive shafts some don't. Anybody with experience on this?
