Don't think any of the DJ waxes are much different from each other, save maybe supernatural. Get a set of panel pots if you want. Remember that 95% of the finish is in the prep work. No wax in the world is going to make a poorly prepped car look amazing.
As for wheel sealant, I use Poorboys. There are loads of others. As long as they're suitable for wheels or high-temps, they should be fine.
