If you are handy, and preferably have a lift to make it easier, you should be fine.
I did mine in about 4-5hrs, being the first time I ever had the diff apart, and I wanted to take my time.
I had a lift, too.
It really helped.
You will need a press to remove the right side shaft, but that is pretty much the only real specialty tool you need, from recollection.
If you do the shafts, do the preload spring washers that place pressure on the diff clutch pack.
I had only about 15k miles on my car, and both OE washers had cracks in them, effectively weakening the preload on the diff clutch pack.
