As with anything in paint care, the less you touch your finish the better off you are.
Junkman's sheeting rinse video is a great example of how to minimize the amount of water you have to contend with when you're drying.
Then using forced air to knock the rest off is idea. You can use an air compressor, leaf blower, or if you're really anal about it the
Blaster Sidekick or
Master Blaster which not only deliver a lot of air, but its heated to 60* above ambient and filtered. Not necessarily requirements, but nice features none the less.
Then once you get done air drying using a detail spray and quality towel to take care of any remaining water should be enough to leave you with a spot free/swirl free finish. A detail spray is key to provide some level of surface lubrication (another layer of protection) as well as encapsulate and make any residual dirt either from a missed spot or trapped in water that runs from door handles, badges, etc to make it safe for towel removal.
