Nope, unfortunately ceramic coating doesn't really help with dust. On the subject of coatings and such, I found that quick detailers seem (to me, at least) to make dust stick to the car more easily (my guess is because they grab the dust). That could be my imagination, though. The California Duster is the best solution I've found if you want to get dust off quickly without washing.
In my experience I think it depends on the fabric type used in the drying stage of a wash. I used to dry with a microfiber clothe and the static or something will always make dust stick regardless what type of sealant or waterless wash was used. Ever since I switched to drying with a chamois I've never had that problem.
