Here is a good read on the ozone systems...........in short they do not work very well for outdoor pools. You will already have a UV system-the sun so........
Ozone Claims
There many other threads about them. Use the white box at the top of the page for more reading.
-tanning ledge height-What kind of chair/lounger, if any, will you use on them? Do you want your bottom in, just over, or out of the water? Use that as at a guide for your depths. There is not "normal" we have found. If it for small kids to splash and play on then.............. If it is for adults to sit on chairs on then this......make it to fit your needs and wants.
-seating benches-where does 18" hit your when you are seated? Is that where you would want the water to be if you are sitting on the bench?
-lights-I like the placements! Should be no shadows in your pool!
-steps-I like where they are in front of the tanning ledge-I might tap it to the left a smige to make sure no one walks off without looking. I would make sure to have step/bench markers for sure!
-Seating bench-I would keep the one in front of the spa and to the side. I might lose the one by the patio though. It would widen your swim lane a bit. If someone want so sit and chat with the patio area they can sit on the spa one.
-pumps-not my strong suit so will leave those for someone else.
-light on tanning ledge-yes! Safety first! If you want to lose a light I would take the one from in front of the spa on the setting bench. I think the one on the step will shine over there.
