Few tips straight away, throw away the sponge and chamois
Then replace with a lambs wool washmitt and two buckets (ideally with gritty guards) and a big fluffy drying towel (see below)

These products will help you avoid putting more swirls in the paint and are the basic products needed, don't use the wash kit on the wheels get a cheaper one or wheel brushes for that.

You will also need microfibre cloths and applicator pads but thats a basic start
A clay bar removes all contaminants from the paint and should be done on a clean car prior to polishing/waxing! This one uses water for a lubracant but most others on the market new a quick detailer

When you get into it more you can get Citrus pre wash, Snow foam & lance, Tar removal, Iron removal, (iron x), machine polishing, sealants, wheel wax/sealants quick detailer, di vessel and other stuff which will keep it looking even better
These are the basic's and some products you can use, there is hundreds of options for products and its up to you what you decide to use
Hope this helps
