Airflow is a good thing.
Lets exhaust gasses out, as well as any other flammable fumes that accumulate in garages.
leave the existing foil backed insulation in place, it won't hurt, add a laver of foam core over it just because more insulation is always a good thing.
install the vinyl siding per the manufacturers instructions.
