Here are some pics of where I was talking about in the back.
Sometimes I jack it up here and use the standard jack places for my jack stands and sometimes vice versa. It really just depends on where I need to get under the car.
Sonoman brings up some good points as well. I always leave the jack under wherever I have it with it snug to the jacking point just an extra support. I also have a rubber pad on the jack and all of my jack stands. Not only does it help protect the places you are supporting the car with, but it also (at least to me) seems that the rubber makes a better surface to resist slipping than metal on metal would.
