Unfortunately, correct. As 68 says, why ruin all your hard work.

Sounds a lot like hard work to me. There are 125mm paint stripping discs that go on a rotary and do the job much quicker and easier. Just make sure your rotary has adjustable speed - you don't want to run it flat out.

Etching primer is old school. Epoxy works better.

No. Block (longer and harder is always better) is much better - will show up imperfections in your panel. A DA will just hide small dents or lows, but you'll see them when the final coats go on.

Epoxy first and then lightly block with P240 and dry guide coat to show up your problem areas. Then do any body work or filling and then repeat, this timw starting a bit coarser and moving up to P240 when it's all flat. From here you can just put a light coat of primer over the top, block again to P800 ready for your top coats. Or do it in epoxy if you want to seal as well. I usually just use primer, but either is acceptable.
One of the big concerns I have is that the paint you're using really isn't user friendly, certainly not for someone inexperienced. You're going to have to buy a stack more in paint and materials. I'd suggest you go with a single manufacturer's system, from any of the majors (Axalta, PPG, Glasurit etc.) Talk to a local distributor - they will help you in selecting a system that is cost effective (not necessarily the cheapest) and has matching epoxies, primers basecoats and clears. Far less chance of something going wrong and, if it does, they can help you recover. FWIW, I use Axalta Cromax and have done for over 20 years. There are others as good, but none that I can honestly say are better. Some of the guys on here have their own favourites - consider these too.
