Hi, I'm fairly new myself and I also have just added some CD's into my limewire library... they do appear as folders, but they are still shared. You should be able to click on a plus sign next to the folder to display the individual tracks... then you should be able to pick which tracks you want to play individually or add them to your playlist in whatever order you want (this is on the limewire player). As for shuffling, i'm not sure about that as I don't generally use the limewire player much, I don't think its capable of that option.
If there is no plus sign next to the folder, then the individual tracks should be displayed when you click on the folder itself.
Hope this helps.
