When replacing brakes, should I..........
also have the rotors turned? I have 74K that is mostly highway miles with low braking but they are starting to make some noise. I also do not get any shimming when braking, so could I just throw on new pads and turn/replace them next time?
... Only change the rotors if you are getting shimming when braking...... you can try Raybestos Quiet Stop (QS) pads to stop the noise.

Sorry, both these posts/answers above are wrong.....you should always turn your rotors when u change pads, for two reasors:
First, not only does turning them make the rotor face perfectly smooth and flat, removes all surface grooves, etc, but it also creates the right surface finish to allow the new pads to 'break in' properly.
Second, all pads transfer some amount of pad material to the rotor face itself. Turning the rotors removes a sufficiently small amount of material from the rotor's face that it's 'clean' of the old pad compound which tranferred over during high-heat conditions.
If you are not shimmying when braking, it means only a few (two, three) thousands of an inch need to be cut off the rotors, no big deal for any rotor longevity issue.
I know brakes. If in doubt, look here. I ws the prototype car for this brake kit and all the measurement for rotor hat offsets, etc were done by moi.

Don't turn the rotors unless they are really grooved. If they are smooth you can just keep using them. You can always just give them a light cross hatch pattern with sand paper if you want to be really thorough. In general, almost no one turns rotors anymore. If they are gone enough to need to be resurfaced, people usually replace them. Turning them is pretty old school.
