Just wanted to share my experience with you guys in hope of saving you time/money. When I first rebuilt my front axle and replaced the rotors with new Toyota OEM rotors (and 100 series pads) from Dan I did not turn the rotors and experienced no improved braking. In fact it was worse, and continued to get worse. After a few thousand miles when I realized driving my car was not safe I began to investigate(full brake from 5 miles per hour took over 10 feet, from 60 it proabably took aver 250 feet atleast). I noticed that I had an abnormal pattern on my rotors. Rather than being uniform like on most cars it was splotchy. I went and had the rotors turned and the breaking is 10x better. I can now break and get a tad bit of squeel.
So in short, turn your OEM rotors before they are installed!
One more tip, do not use a puddy gasket for your diffs. When I went to 4.88s I forgot to order new gaskets so I used a puddy gasket. About 2000 miles later it began to decay from exposure to the 4x4 environment and I began to leak fluid from my diff. Needless to say I am now ripping my knuckles apart one more time to replace the puddy gaskets with OEM gaskets.
