Yes, that jack has the height to lift to the top tier of the stands without spacers. But I do use a block of 2×4 under the diff and a 2ft length of 2x4 under the front chassis for lifting. I had the 4x4 block handy if I needed it but I didn't.
It looks tall, but its a small car. The car is only 17 inches up, floor to chassis.
As for step lifting, I already had been on wheel dollies so the angles were not too extreme. If not, then yes, I would be lifting the front and back in steps. Probably just two steps.
Another note, as these stand bars are only 30" long, and the verticles are spaced 23", I wasn't comfortable with that on the rear where the chassis is 39". I cut the rear stand in half and extended it 13".
1.25x36" square tube from Home Depot is a perfect fit inside.
