First: Limewire sucks for torrents. Use either µTorrent - The Light****** and Efficient BitTorrent Client or Azureus : Java BitTorrent Client (You will find links on how to setup the clients on the respective websites)

If you choose Azureus this might come in handy as well Main Page - AzureusWiki

Also: Bittorrent - Bit Torrent terms and definitions

You download and open the torrent file with the programs.

BTW Google is a great way to find torrents as well. Type "what you are searching for"+torrent in the search bar and press enter, then read the comments if available before downloading. There are many fake torrent files on public torrent indexing sites as well.

Second:

Finding better quality movies

Limewire 4.12.3 / Newest Phex / Newest Azureus

I recommend using either an old Limewire version without BitTorrent support or Phex for Gnutella, Azureus is BitTorrent. None of this Limewire Gnutellatorrent hybrid crap.
