Yes it sounds like your power steering belt needs changed also you need to check the power steering fluid and the tension of the belt whereas the belt might be loose. If this is accomplished via a belt tensioner then the tensioner probably needs replaced also.

Oil in the distributor will do that. But why is oil getting in there? The positive crankcase ventilation(PCV valve) should prevent this. Plus the should be one seal on the distributor and /or cam. I would pull the distributor and check for sloppiness. Also check for the cap seal. Oil could be from the valve cover.
