First...64 kbps isnt meant for downloading/torrents...try getting 256 kbps atleast.
Second....the main principle behind torrents is sharing;without uploading, there's not much downloading. For eg., if u set ur upload limit to 0, then most peers(except seeders) wouldnt keep u and will disconnect from u....so ur download speed will also suffer.
If u dont want to upload, then try P2P like Limewire,Shareaza etc. but they arent really as good as torrents.
