With the exception of Chicago
😉, I've been to every place on your list. I live in Montana (approximately 50 miles north of Yellowstone Natl. Park) and have spent a considerable amount of time in the Southwest. A few points to consider:
Some of the most popular national parks will have a shuttle system during the high season -- Grand Canyon, parts of Zion and Yosemite. This may be an issue if you're the type who likes to be on location before sunrise and after sunset.
If you want to see wildlife, Yellowstone is tough to beat. If scenery is more to your taste, Glacier National Park is a better choice than Yellowstone, IMHO. (But Glacier is definitely more of a detour from your intended route.)
Moab and the surrounding area is a good place to set up base. Arches N.P. is right out of town and Canyonlands (Island in the Sky unit) is only 33 miles away. Campsites within Arches will be scarce. You can either stay in a commercial campground in Moab or you may have better luck in finding a campsite in Dead Horse state park or in Canyonlands. From Moab, you can head south toward Monument Valley and take detours to areas like Mesa Verde or Chaco Canyon, if desired. Then cut across northern AZ toward Page and hit Antelope Canyon (upper and lower). The slots are best at midday, which is great since the light is crappy for any other shooting at this time.
The areas mentioned will be busy. Yes, while it is great to get off the beaten path, since this is your first time out west, you just need to deal with the other park visitors and see these areas. You'll then know the areas you will want to revisit on your next trip.

Regarding equipment, I think that you will probably benefit the most from a DSLR kit, and if shooting film, some medium format gear. I utilize both large and medium format film cameras for my landscape work. When mobility or time constraints are an issue, I have found my Mamiya 7II kit invaluable and this is often my "go to" camera.
Since you will be car camping, you won't have to skimp on comfort. Forget the thin, lightweight sleeping pads for backpacking. Go for something cushy. I have an LL Bean self-inflating "camp futon" that feels simply luxurious. Sometimes I have a tough time rousting myself from my sleeping bag for those sunrise shots!
My last bit of advice is that which I often tell myself -- either cut your itinerary in half or double the time spent on your trip. There is so much to see and do and you will only scratch the surface! Enjoy your trip -- you're going to have a wonderful time!
