I'd get the upgraded output shaft as well. The labor on the diff replacement is rated around 10 hours.
No need to do it twice.

I think an upgraded shaft would be a bit redundant. The car will never see hard launches, DRs, or 1/4 mile runs.

I'm still getting 26mpg on the interstate in 6th gear with my new cam and 4.10 gear. 
A 4.10 made my RPM @ 70ish go from 1400 to 2000. No big deal
