At the front, I place a jackstand where the body seam turns inward toward the motor. This is in front of the forward marks and about 6 inches inside of the rocker facia. At the rear it goes just inboard of where the body seam ends. You'll have to get under and look to get an idea of where they go. I don't have any pics to show the locations but once you look at the area, it's pretty easy to place them.
When I jack up one side, I set the stands at their lowest height then raise the other side of the car to the same level. Then I go back to the other side and go up to the height I need and finally do the other side. It's a bit tedious but it is safer that trying to jack up to the desired height all at once.
Just make sure to pop the door and hood latches before starting.
