The sauce should be fine.
The Cheese - you would be better off vacuum sealing and refrigerating it for long term storage if you want it to retain it's original texture. It probably should not be frozen unless you're going to use it in a recipe where it will be incorporated into a sauce or melted ... cheese tends to get mealy when frozen - but when melted that isn't a problem since the texture is naturally changed.
