Answer 1

There's a firefox add-on Dust-Me Selectors that will find unused CSS selectors.

Answer 2

I'm not sure about doing it in Visual Studio other than doing a Find In Solution for each CSS rule / Skin / Image.

To find unused CSS rules, you could use the PageSpeed add-on for the Firebug add-on for Firefox. This will analyse individual pages of your site and give you a load of info on how to speed it up, including removing unused CSS rules. Might be helpful!
