White smoke is water. Could just be condensation in the exhaust. Could also be a blown head gasket (which would explain the smoke and the rough idle. Are you losing any coolant?

Then it is probably just condensation in the exhaust. Have you run a compression check on the cylinders? Fuel pressure check at the rail? Are you getting a check engine light?
