From one beginner to another, I would recommend keeping it simple. Here's what I would do if I had to start over. I would order this kit:

With extra pads of each type. You'll need a pad cleaner as well.
I would recommend Menzerna Powerlock as a sealant. I prefer applying by hand than by machine. If you want to use the machine, there are pads specific to applying sealant.
You'll need a boat load of microfiber towels. I have ~15 and between compounding, polishing, and IPA wipedowns, I washed them 3 times.
