Ok, where to start.
So like everyone has said about the rear, reset leafs work well, but, if you want it low the springs will be inverted and the ride won't be the best. (Who cares about ride quality anyway, it's all about the look)
Now the front. Coilovers are a good option although all the ones I have experienced have been harsh and decent bumps feel exaggerated through the steering. Most shocks are to 'heavy' for a lightweight 10.
I haven't found a great setup yet, although I am looking at going back to an oil filled shock (feral4k might chime in here)
after a few years on the road, I've managed to bend a strut tower and its support that goes to the firewall. My opinion on this is that with the leaf removed all force is put through the strut towers and not transferred through the front crossmember.
unfortunately when it comes to ke10s there really isn't a lot of good info around and its pretty much trial and error.
