You might as well consider higher ratio now, no point paying twice.
No new RP needed. I've heard new TT's come with 1/2" carrier holes. If not it's no big deal having them drilled. I had my first real test of my front/rear TT's recently driving over the continental divide in Wyoming. It was almost a white out and 50+ cross winds and black ice AT NIGHT.
I watched several cars skidding off the road in front of me and noticed I was on black ice going down hill at 60mph. It was a hair raising experience. After that I had plenty of shifting back and forth from 2h and 4h. Lots of snow/swirling snow. Even the semi's got off the highway. Although I was only going 25 mph most of the time traction was excellent. One TT in back made a difference but using both worked great. I never felt out of control, and Traction Control never came on once.
I highly recommend getting a TT, but stay away from the mountain pass over the continental divide through Wyoming at night in a snow storm
