Make sure you have firebug (for Firefox, if you don't know), and then install the pagespeed plugin for firebug, developed by Google:

http://code.google.com/speed/page-speed/

It will give you a 'pageSpeed' tab in firebug. Open it and, with 'performance' selected, click 'analyze performance'. Along with lots of other useful suggestions, you will get a list item labelled "Remove Unused Css". Click to expand it and see a breakdown by resource of unused css rules appearing on the present page, along with the memory size that you will save by removing the unused rules.
