No. Claybarring removes pretty much anything stuck on the paint, wax included.
Polishes shouldn't leave anything behind (realistically). They're job is to buff scratches out. It uses abrahasives (or chemical treatment) to very finely polish the surface, then they're wiped clean. Wax leaves a coating to act as a shield against the elements.
Claying should only be done once, maybe twice a year (I like once in spring, then a new one in fall in preparation of winter). Again environemnt will affect it. Unless your paint takes a beating everyday, than once in spring should be fine.
