I had a lot of wma files so I let iTunes convert those to .mp3 ... I would like to delete all the wma files

You don't want to do that. The WMA was less than CD quality to begin with and by "converting" them to MP3, you've reduced the quality even more. It's like a photocopy of a photocopy. Why do you have to have them in MP3 anyway? Did the WMAs not work?
