Okay here goes:
1. Torrents are available. SUSE 9.3 is available from
http://www.interknet.net/bt/?torrent=suse93
2. The Live DVD is not installable.
3. The install CDs of 9.3 Pro have both the 32-bit and 64-bit versions. [The full DVD has sources as well, that's why it's twice the size.]
4. SUSE 10 is due for release on the 6th of October.
www.opensuse.org will have links to download it (5 CD images) either by FTP, HTTP or Bittorrent. There will of course be i386 and x86-64 versions. Currently you will find the first release client available for download.
