I'd highly suggest a clear bra. Our toyota paint is kinda easy to chip. I never drive close to anyone in front of me and i still have a chip on the hood, and 3 on the bumper.
Next, I'd look up how to wash with the two bucket method. learn it and use it. This will be the biggest step in keeping your car in an "autopian" condition.
for the CSM color, I'd go for a sealant like UPP. It seems to brighten up the paint a bit, give awesome slickness, and give a more pronounced metallic flake pop. Use it over a washed, clayed, and AIO'd surface and your good to go. I'd apply 2-3 layers (24 hours between layers) and pick up some UPPS for after wash maintenance.
