Paul, There are a couple of tools you could use. Mac Janitor is one, the other is Onyx. Be sure to get the version for your operating system. Ithink each has a version for 10.4 and another for 10.5. Also another great one is called Applejack which mounts before anything happens allowing you to do a lot of mainteance stuff without using a startup disk. I generally start with that one before doing anything else.
