@dee00,
Just to be clear what you want:
To remove the torrent content (music/video, etc) from phone, just go to d/load directory and select delete.
If you remove a torrent from desktop uTorrent client, the listing .torrent files remain in client's app data folder (Computer>Local Disk (C):>Users>Username>AppData>Roaming>uTorrent). You can select and delete as required.
You can remove the listing from uTorrent Android app on phone, from memory it's long tap then delete. This should remove the .torrent file that facilitates the content d/load. If not they're only a few KBs per file, and there's the option of deleting app data in Settings>Applications manager>All>uTorrent.
Hope that helps.
