Changing the rear spring is easy and can be done in a half hour or less. Changing the rear end will take some time and is rather awkward without the right tools and support.

I do mine on the garage floor and use a floor jack fitted with a lifting bracket I made for the diff. I take the batwing and all for the simple fact I don't like dealing gear lube until the unit is on the bench.

Getting a set of Beam Plates from Bill B will make reinstalling the unit a bit easier.

I also suggest you support the transmission where it is at and remove the C beam so the shifter boot stays intact and in place so you don't have to re seal it later.
