500mb actually goes a long way, most of our customers run on the default settings with no problems. If you are doing a ton of caching or have A LOT of class files being compiled to memory than it will shoot up pretty quickly. You can use the CF built in server monitor to determine where memory is being used, app scope, sessions, cached queries etc, which may help you determine if the memory usage is expected or not. But if you have 8GB available then no probs giving 1GB to each instance.
Isolating sites with their own instance is always good, especially if you have the resources to do it. We have a setup called "semi-dedicated" where we have a limited number of sites per instance, and it very rarely causes us any problems this way.
