How about putting all of your cylinders inside a union and 
then giving the union one material, leav out any cylinders
that you would like to be different. 

#declare CommonMaterial =
material{
         material directives in there......

        }


#declare Most_Of_The_Cylinders =
union{
      cylinder....   rotate... translate...
      cylinder....   rotate... translate...

      material{CommonMaterial}
     }

object{Most_Of_The_Cylinders rotate... translate... }

Hope some of that helps.
