will this work with new headlights?

Scott Kilmer did a test on new headlights and he recommends using it on new headlights. I suggest you look for yourself on YouTube.

What is the best way to remove the old coating of this spray coating? The coating is peeling off about 8 months after I applied. I want to re-coat.

Rather than grinding everything down again with a typical sanding restoration kit, you are much better off using Mother's 0510 Mag and Aluminum Polish (available on Amazon). Apply it to the headlights using a buffing sponge (either by hand or power). This will remove the old coating without taking more of the plastic off. When I've done this using an attachment (Thikpo 12 piece 3 inch buffing pads available on Amazon) to my drill, it literally took less than 5 minutes per headlight.

Does this product need to be removed from the headlight assembly before reapplying within a year?

I reapplied after 14 months, the headlights had a lot of dried Lovebug juice, it is hard as a rock, so I had to clean it. Tried a few bug & tar stains removers and they didn't do anything. Then tried Solimo 99% Isopropyl alcohol sold by Amazon and it took it off. I also notice the original coat of the Meguiars Headlight Coating had hazed a tad, which was not apparent till I fully finished the first lens and compared it to the other side which I had not done yet. The alcohol will haze the lens, but that it just because it dilutes the old headlight coating as it takes it off. You need to use a paper towel cut in 4 pieces and wet it and use one side to clean, then turn it over and use the other side and keep doing it till you are sure all the headlight coating and Lovebug juice is off. Then polish the remaining haze with a dry paper towel. At least that is what I di and it worked great and was easy work.

Is there an alternative to coating like this? I see plastic polishes with wax? Probably need regular application

Wax based coatings make pretty, but don't last. Can also absorb bug goo & other contaminants. This is hard, non-porous coating that is surprisingly durable. CLEAN EVERYTHING FIRST!
