I'd go for the Sonus Wool Mitt and Der Wunder Drying Towel, and a couple of good plush Microfibre cloths for buffing. Don't forget applicator pads too, these are only a couple of quid.
Autoglym SRP is a good and comparatively cheap polish that has fillers to hide any swirl marks. With regards to wax, I'd pick up some Collinite 915 or 476 which are both very long lasting - handy with Autumn weather about to kick in.
That would be a good kit to start you off with, everything else you can build up over time when you get a better idea of what you want.
For example - you might decide to invest in a wax or sealant that complements your colour well, you could then add a layer of Collinite on top of it for extra protection, as you've already bought some.
You could also invest in a clay bar now though, the Bilt Hamber Regurlar or Soft are supposed to be excellent - although I've yet to try one.
