Default Rear gear change

Am planning to change the rear gears in my 72 W30 4 speed this spring and would like some advice from the experienced.

The car originally came with 3.73:1 posi but somewhere in the past was changed to 2.73:1 (it's really pretty sad.....).

I usally go to several shows where I drive 45 minutes to an hour on the freeway. That's really abou the worst of it. The rest is 35 - 50 MPH to the local cruises and shows.

I want to have fun off the line when I feel like shredding some rubber. Should I go all the way to the 3.73's or would I get about the same rush from a change to 3.42?

Also, I have never done this before but am certainly mechanically inclined. Is this a do-it-yourself project or better left to professionals? I'd love to do it myself if it not too risky.

Also, what parts do I need to get? Gears, bearings, clutches, axle seals? Any other tips or advice?

I can't wait for Spring this year!
