Nah, it's not as bad as the front. You'll need new spindle nuts and if the wheel bearings haven't been touched in a long time then now is a good time to replace them. Make sure you pack them good with grease and use a new wheel seal with your new rotor. Grease the lip of the seal. Also with the brakes clean and grease the slides for smooth operation.
You'll see 4 mount bolts, two are for the emergency brake assembly. There is no need removing them, just the two for the caliper.
You can go to techcapri and download group 12 brakes for illustrations and instructions including the spindle nut torque.
