I'd get yourself onto Detailing World, have a good read. Just remember, some of them on there think you need a 40 stage wash & decontamination session lasting 3 weeks.. You really don't need as many products as you think if you're starting out. I've got an old school Kestrel DAS6, had it for about 12 years & it's never missed a beat. I have a couple of 4" pads, 6" pads & 2 polishes, that's more than enough for me for my usage. A couple of tins of wax, a clay bar & a few other bits, you certainly don't need a whole lockup full of the stuff.
