There are several shows where the husband is a child-like bumbler and the wife is in control or more mature:

King of Queens
According to Jim
Yes, Dear
Everybody Loves Raymond
Malcolm in the Middle
George Lopez

Are there any shows where it is reversed and the wife is the goofball and the husband is level headed? (Dharma & Greg?)

The prime example of the goofball wife/level headed husband would be "I Love Lucy". Another similar example is the lesser known Jim Backus series "I Married Joan". You could also put "Bewitched" into this category.

A good example would be The Nanny, but technically only the last season would count, when Fran and Max were married.
