Should I have NOT had my external hard drive with Time Machine connected during the upgrade? The reason I ask is in the Installation Instructions on the 10.6 disc it says:
"After you have installed Snow Leopard, connect Time Capsule or an external USB or FireWire drive to your computer and use Time Machine to make an up-to-date copy of everything on your computer".

Are you installing in place (i.e. a standard install) Snow Leopard, or did you erase the drive first?
Are you using the retail SL disc
Are you booting from the disc (holding the C key on startup) or installing from the desktop?
TM has it's uses, but a better solution for this situation is to clone the Macintosh HD to a seperate external HD. You then can boot from that clone if needed.

I was installing from the retail SL disc. After the 3 install attempts described above I wondered if Little Snitch or Norton Antivirus could be causing problems so I uninstalled them. Snow Leopard installed perfectly after that! Thanks for those other tips, though.

If any, Norton was the problem. Throw it away; it doesn't play well with Macs. You don't really need AV software, but if you need the security blanket or swap files with Windows PCs, ClamXav is free, as is a lite version of Sophos.
Little Snitch is a valuable tool, but you should switch off the network monitor before Installs, security updates etc.
