If you're not going to rotate your own tires, I would just get a set of ramps to run up on to do your oil changes, much easier.
If you are going to do your own tire rotations, then your floor jack and stands will be needed. I use the metal edge on the sides running between the front and rear tires. Jack up behind the front wheel leaving enough room to place your stand in front of the jack. Do the same for the back.
Still, I always feel better on ramps when laying under the car.
