I have a 91 4-cyl Camry auto too.
I've done both sides so I may be getting mixed up, but...
I am pretty sure the 8 bolts are on the drivers side. I just loosened them up. Everyone says you can use screwdrivers to pry on the lip on the inner CV joint housing, but when I did it I used a slide hammer that I rented from an auto parts store. It came in a body repair kit and had a hook I could hook onto the lip and then GENTLY hammer it off.
For the passenger side, there is a C-Clip. I had trouble finding it the 1st time I did that side. Keep in mind this pic is for a 1mz-fe which is different from the 3s-fe you and I have. But, anyway the c ring is in about the same location. On the pass. side, there should be a bracket hanging down with a large round bearing/wheel on the axle that spins in it. The c-ring is just outside of this (toward the wheel on the pass. side).

Good luck!
