Welcome Dave. Your plan and current supply list is great. I would switch the order of Buttery Wax and H2O G&G, simply because G&G on its own can last a few months (Indefinitely when re-applied every few washes), but your buttery wax will only last a few weeks or so on a daily driver (I'd say at least), so once your wax burns off then so will your H2O G&G with it.
If you're using the Buttery Wax before the H2O for a shine and luster enhancer and hoping to lock it in with the H2O then I would axe the Buttery Wax, using it only as a top coat, and then use Brilliant Glaze which has shining properties only, and then go over that with H2O to lock it in. Other more experienced detailers can step in with that.
Basically you want your more resilient products as close to the paint as possible. So you'll also want to make sure that the wash you give it before applying LPS (Liquid paint sealant) is a strip wash, getting rid of all old waxes, coatings, sprays, and soap film.
Re-Wash when needed, dry with H2O to maintain the sealant. Eventually your paint sealant will die off, say about 5-7 months, then you'll want to Re-strip and re-seal etc.
Good luck and have fun.
