I'd recommend changing the transmission to an 8L90 or 10L90. Both will give you better overdrive than the 6l80.
You can go aftermarket for Ring and Pinion. Terrain tamer sells different gears. Not sure how low you can go. But I'd leave it with a factory ratio for simplicity. It's always easier to source of the shelf local parts than it is to order something unique from overseas.
in my 105, which is essentially an 80 series with a 100 body. I did an L83 swap with the 6l80. My cruiser came with the 4:30 gears in the diffs. The ratio is steep from the factory to help the original 1HZ. Long story short, I swapped the gears to 3.73 from the UZJ100.
If I was to do this again, I'd go with 8 or 10 speed transmission. You'll get better range than the 6l80.
Good luck
