you could clay as you wash providing you have a constant flow of water to keep the surface lub'd. or you could wash, then clay, then re wash, then dry.....Allways clay a cleaned surface, and be sure to use plenty of lub, either ready made or home made, kneed clay often making sure your not using contaminated clay, then up n dowm all over panels with slight pressure...Once you have clayed the vehicle put a liner from a pack of bensons on your finger tips and rub over car to see if you can feel any missed area's(trade secret that, so dont tell to many about it)
I used meguiars quik clay and kept 'misting' the panel I was doing as I went along with the quik detailer that comes in the kit, really simple to do! Apparently you should have the clay soft and also the paintwork not hot, no real chance of that this time of year!
There's a handy guide Here, kindly demonstrated by a lady with some big tats
Quote of yesterday for me... lol
I used some car shampoos (poorboys for example) in a plant sprayer to keep the paint well lubed.
Take your time with it, and if you drop the bar on the floor, dont use it again on the body work! - by all means use it on your wheels. For this reason I dont use a massive chunk like that lady with big "tats" 
Have fun, its quite relaxing. I only do it about every 3 months.

Delicate laquer on your wheels?
Its not really worth the risk for a 7 squid clay bar
Depends what wheels you have, how much you treasure them and how much disposable income you have really! The clay bar is going to pick up so much stuff from your wheels anyway, it will have a similar effect unless you keep kneeding? it.
