Not sure what state you are in, but I recently got a quote for a 6.7L in GA. 8 hours for rear axle and 10 hours for front axle at $155 per hour. That wanted me to purchase and bring in the parts.

20 hours.
Go 4.56 for 34" tires or less, if you want to be conservative. For performance, go 4.88 and dont look back.
Forget about 4.30. Not a big enough change to be worth the cost.
Put a Detroit locker, or Yukon Griz locker, in the front axle at the same time. Diff has to come out for gears, minus well upgrade.
