There are many many ways to do that depending on how much control you want. The one below is my personal favorite. Few checkboxes and ObjectTags. I'm not even using render masks so it all renders in one pass. Much easier to setup than Compositing Tag and it gives you much more options in post. Also, no headaches about what light is assigned to what piece of geometry in a big scene. You can reuse the same setup in Ae, Fusion or Nuke for different products instead of dealing with individual pieces of geometry every time in every scene. It's easier to adjust intensity or even color of each light/reflection... etc.
