Never clay unless you plan on polishing after. Washing correctly in less frequency will give your clear coat a longer life span of being swirl free. I wash once every 2-3 weeks or twice a month. Avoid any drive through car washes. Keep your car waxed in between, I personally use spray wax.
Here are the links to basic products that I would suggest to maintain the paint. I recommend purchasing them on sites that have frequent sales, usually around 15% off.
The two videos will teach you the traditional washing method, the other is for a waterless wash system. Again, the point of these techniques is to cause less chance of dragging any debris or particles across your paint. Oh, and go get a pressure washer from Costco, there's a decent one for around $200. Trust me on this one.
