As you can see from my "member" status, there are many more qualified people here to answer your questions but I do have experience with the products to mentioned.
Firstly, unless you need the exercise, I would tape that chrome and use a power buffer to correct the paint. It's pretty hard to screw up and if you start with a nice non-aggresive final polish, you should be fine. I have a similar "batmobile" that does not see the light of day very often and I'll share how I take care of it.
Once you get the paint where you want it, a nice beauty coat of wax (Pinnacle looks awesome) or if you want something with a little more staying power, Fuzion. I'm not sure if I would bother with a sealant on a car that does not sit out. I've tried it both ways and honestly can't see much difference.
That having been said, maybe the sealant will provide a little more protection for the waterless/rinseless wash it sounds like you are going to have to use to keep the interior dry. I use some big fluffy Cobra microfibers (about 3 per wash) to do a BMW of similar size. This is where the swirls will happen so more towels are better than fewer.
I can't remember the last time I waxed any of my cars because they "needed" it. I usually do it after I go crazy on a sale or something new comes out. Nobody bothers me when I'm in the garage...
If your paint guy did a good job on the finish, you may be happy with just the paint cleansing lotion and then the wax. The lotion has the ability to fill in some very minor swirls and yes, it strips the wax under it as does the polish. If you're careful with the wash, you won't have to polish very often at all. Just freshen the wax up with either more wax or spray deatiler and go win a trophy! I got a freebie bottle of Pinnacle spray wax and it really looks good! Those rascals have sold me two more bottles since then
I just bought a gallon of Optimum No-rinse and I love it (mixed in a bucket and used with 2-3 fluffy towels). It also makes some sweet clay lube and I would recommend claying with a light clay before putting in the rest of the work. It was around a body shop at some point so I would be shocked it there was no overspray at least somewhere on it. Besides, I think it makes the wax lay down nicer.
Hope this helps, it was windy enough! You're going to love how it looks when you are done
