Question 700R4 Conversion Driveshaft Length

I just purchased a 700r4 for my '72 C10 Longbed with a mild 383 and would like to know if anyone can tell me how much the driveline (2-piece) should be shortened. The TH350 I am dumping was original.

Also, I have 3.08 gears in the rear and know that I will need to swap. Any advice on 3.73 vs. 3.42?

Does anyone have advice on a limited slip or posi unit? I figure I should saddle-up now to install when I have the ring and pinion replaced. The rear axle is a stock 12-bolt. What should I expect to pay for labor to do the rear-end if I buy the parts?

Thanks in advance for the help. This MB has been a tremendous help in this project.
