I have some prewritten css that I use for a bunch of sites to integrate different things, is there any kind of tool that will go through and eliminate the styles not being used? Not all of them are used by every site and I dont really have time to go through them one by one. Thanks.

You can point out what selectoris are unused. You can do this with a Mozilla Firefox extention. It is called Dust-me Selectors, just google to find it. Bye
