First, you'll want to raise the vehicle off the ground and secure it on jackstands. I find it easiest to drive the front onto ramps (if you can fit them underneath), jack the rear in the air (using the diff housing as the jack point) and place a jack stand on either side (i.e. the scissor jack points). This will give you room to work underneath while still maintaining a somewhat level angle.
The green circles indicate the fill plug/hole and the red indicate the drain plug/hole. Break loose both bolts and take out the fill bolt first. Keep track of the crush washers (they sometimes stick to the casings and/or fall into your drain pan). You may notice some fluid already coming out at a slow pace--this is normal. Place your finger over the fill hole and remove drain plug (this will keep things a little cleaner). Once you are out of the way, remove your finger and release the fluids (a fair amount will already be coming out). Allow to drain until you see drops rather than a stream. Clean, replace the drain bolt (flip the crush washer around if you don't have a new one) and torque to spec. Fill with proper fluid (I find using a suction gun works best). Once fluid starts to seep out of the fill hole, you are done. Clean, replace fill bolt (flip crush washer around if you don't have a new one) and torque to spec. Spray with brake cleaner to remove any excess fluids.

My first change at 3500mi showed a good bit of shavings on the plug:
