The condenser is the radiator shaped thing in front of the engine radiator. That's actually your accumulator/drier assembly but it does take moisture out of the refrigerant system and locks it in a dessicant (sp?) material. The whistling that you hear is the pressure equalizing in your refrigerant system through the orfice tube when the trucks AC is off. Yes the condensation is normal also.
