Hey Dan,
You can go mad in this field. I, like you, like to keep my car in excellent condition! Firstly, don't use a sponge or chamois. They both scratch the car's paintwork by rubbing the grit that is on there into the top layer. If you could get a wash mitt and a microfibre drying towel, you will dramatically reduce this! By also using the two buket method(bucket with soap, bucket with clean water to rinse your mitt after every panel to remove grit) you will reduce this even further. I know it may seem over the top, but when you look at a lovely car but it has spiders webs all over it, it spoils it.
I would seriously recommend claying the car to remove contaminants from the paintwork, it makes a massive difference, you'd be amazed!!!I use a DA polisher on my cars, which rermoves these swirls/cob webs with a [polish, but you can fill them with Autoglym super resin polish (AG SRP for short) Or poorboys world black hole by hand. Once you've done that, a good wax for longevity is Collinite 476s. This will protet your car for 6 months with a couple of layers. Then its a simple task of using a speed detailer once you've washed it at the weekend to enhance the gloss and maintain the protection. It may take you a few hours but this process would cost you over £100 done by someone else!
A decent washing guide

Pick through the processes you want to use, but as a basic treatment, I'd go rinse, wash with mitt and 2 bucket method, rinse, clay leaving car wet and using detailer spray as lube, polish using SRP, wax using collinite!So a wash mitt, 2 buckets, microfibre drying towel, SRP/poorboys black hole or another filler, collinite wax or even Finishkare 1000p for a really glossy look!!! the werksat products are really good, but don't think they contain fillers, so any fine scratches/swirls will not be masked. However if you machine polish, werksat will enhance the finish massively. I'm sure some of the more seasoned detailers will give you their opinions in a little while.
Hope this helps, Sorry if this comes across as teaching you how to suck eggs, but was unsure how much advice you wanted.
