Should i still lay down the recommended 1/4" fanfold insulation over the shingles to act as a vapor barrier even though there is no heat in the building? Jason

No reason that you need a vapor barrier if the space is unheated. Make sure that you lay down a slip layer to protect the underside of the metal roof.
