Firebug is helpful, and I've also found Google Chrome to be very helpful without any plugins. Just highlight the area you want to change, right click, "Inspect Element", the new window that pops up lets you see all the elements on the page, and the one you've selected shows you all the css that affects it on the right side. Everything that is overwritten by additional css files is crossed out but still visable, and you can see exactly what css files the attributes were set in. Kind of handy, but yes I also definitely see your frustration.
