with 34" tires I'd go with 4:11 gears because you have no overdrive . As for shifting early, my 97 did the same, I adjusted the downshift(kickdown) cable about 1/8 inch (tighter) and that helped alot. It is much more driveable and I no longer have to keep it in 2nd on the backroads.

He who knows not and knows he knows not, he is simple, teach him.
He who knows and knows not he knows, he is asleep, wake him.
But he who knows, and knows he knows, he is wise, follow him.”
