Any way that works for you is a good way to work. I use layers extensively myself and I often move objects between layers as the scene evolves. Its especially usefull when setting up lighting to have each light in a different layer so you can render the scene with each individual light to see just what it is affecting. I've only had one scene that I had to break up into multiple renders due to the number of objects and poly count, and even at that I could have done it all in one render if I had a bit more patience.
