What type of noise is it? Rhythmic, or constant? During braking only, or all the time? Have you checked to make sure the shims haven't wandered into the rotor?

First, you should turn the rotors ONLY if they really show signs of needing it.
Second, it is impossible to get a "good" answer to a question like this unless someone replies with the same model "truck" and who lives in the same town.
The "fair price" varies a LOT from place to place.
Rotors should also be turned any time the pads are replaced to allow for proper bedding and reduce chances of noise.

Due to the age of your coach, I highly recommend new calipers, to prevent caliper stocking problems later.
My preferred pad is the NAPA ultra premium. They tested the best of all pads on the Michigan State police tests. They are not cheap. Retail is $115 but they have sale often, and if you have AAA there's a discount there.
Unless the seals show signs of wear or the bore is scored, I'd recommend just making sure the pins (assuming E350 uses a sliding caliper) are greased and in good order.
NAPA UPs are good pads though. Low dust.
