Rotors are pretty easy to install. I'm not home to see my manual on what your exact setup is, but here is the basic rotor installation if it has bearing races in it.
First, remove your calipers from the brakes (should be two bolts on the back of the caliper). Use a coathanger or something similar to hang the calipers from. Keep the calipers from hanging from the brake lines, it can damage them. Then remove the cap off the center of the rotor to get to the bearing nut. Remove the cotter pin from the bearing nut and remove the nut. The bearings and rotor will come off easily. (If you don't already have them, do yourself a favor and buy new seals for the new rotors.)
Pack the new bearings with grease (or if you use the old bearings, make sure they are in good shape and packed with grease). Install the rear bearing in the rotor, and tap your seal into place. you can do this with a block of wood, or a large socket. Make sure it is fully seated. Put the rotor on the spindle, install the bearing,washer and nut, and torque it per the spec. Install the cotter pin and bearing cover. Install your new pads and put the caliper back on.
