I have a 94 Toyota myself. I would avoid the 6-inch lift as well. I have OME shocks at all four corners and some aftermarket rear springs that give a small height increase over stock as well as ball joint spacers up front. I'm currently running 33x10.50x15 BFG A/T tires. I'm still running stock 4.10 gears, unfortunately, but it's not as bad as everyone says it'll be. Sure, the trucks a dog on big hills but it was before the tires too. I'm still getting 19mpg on the highway loaded with camping gear, tools and with my camper shell (with Yakima racks) on.
I say go with OME shocks and BJ spacers and some sort of new rear springs. Don't be afraid to run the 33's, but try to regear as soon as possible. I hope to later this year, but money is tight for me so we'll see.
One more thing, if you do the BJ spacers up front be sure to get the correct offset wheels. Some wheels have an offset that puts the wheel to far in which will cause rubbing on the upper A-arm. I'm running stock (86+) SR5 aluminum wheels.
