You could try using a resource editor, such as ResHack, or PE Explorer.
ResHacker is free, but its a bit limited, as its an older program. You can get it here:http://angusj.com/resourcehacker/
PE Explorer would have to be my favorite. It's quite extensive, but it does cost a bit, if you're the type that buys their software. You can get it here:http://www.heaventools.com/overview.htm
Either way, both programs should be able to do both things that you want to do.
