If I remember correctly, I just had my arms out to replace my rear wheel bearings. Take the rotor off and take your parking brake out. Disconnect your parking brake cable. A slide hammer makes taking the rotor off and replacing it a piece of cake.
Get three steel lug nuts to use with the slide hammer if you use it or you will ruin your aluminum lug nuts.
You have to disconnect the half shaft (cv joint) from the hub. Because you are taking the arm out you may be able to get away with only disconnecting the half shaft at the hub rather than removing the entire shaft. Now would be a good time to remove the entire shaft and repack the cvs with grease anyway. Make sure you "wake up" the screws before you try to remove them and make sure they are well seated in the screw head. They should come out without a problem nut can be easily striped if you are not careful. If you strip it you can use a pair of vise grips to get it out.
Next to would disconnect the parking brake cable's little brackets that are screwed onto the arm to get the brake cable off the arm. These brackets hold the brake line as well and there is a disconnect for the brake line on the last bracket.
You have to remove the lower shock nut and bolt that attach the arm to the shock (very easy), remove 3 nuts and bolts along the arm that hold it to the car (mine with covered in grime, but came off without a problem), then remove the nut and bolt on the upper part of the arm (this one too was fairly easy to get off).
Within the three nuts and bolts that are together there is an oblong hole that will adjust your alignment when you put it back together.
I think clarks has a write up for removing them. Check there and see too. He would have to torque specs as well.
