If you get after 'em right away, they'll come off with just picking with your fingernail. At least mine did. If it won't, try naptha, otherwise known as cigarette lighter fluid. It will loosen the adhesive and won't harm the paint. Just don't smoke while you are working on it!
Just used it to remove all the emblems off my '04. You can do a search on de-emblem and find all kinds of info on this topic.
