I don't have the Min Rotor thickness for my Front or rear rotors. Does anyone happen to have this handy? Mine look pretty bad. I'd like to have them turned.

If they have never been turned you are pretty safe. The minimum thickness is cast into the disc(on the back i think). It will be different from front to back.

FWIW my Chiltons has a pic of one that says "Min Safe Thk 27.2mm (1.07in)". I cant tell you if this is a front or back, EXT or regular TB. THis would be good info.
