If I understand correctly:
On the backup question- when you start to install many / most programs, they will recommend backing up first. Somehow they feel if that if your disk crashes they can say "I told you so".
Whether you use a wizard or copy them to CD/DVD manually is not important, though many backup programs will keep track of what you have already backed up, and if it hasn't changed, it doesn't back it up again.
The whole idea is to have whatever you can't stand to lose stored somewhere besides that hard drive.
We all follow a periodic backup plan, don't we?

Some like to copy the registry to the desktop - it's visible if you come back in safe mode.
Also, check the "DO NOT CLICK DOWNLOAD IF YOU ARE UPDATING JUST ONE COMPUTER" part of the link Tarq provided. It may apply. I don't think you've mentioned your connection speed - it will take a while. Supposedly you can also just turn on Auto update. I'd rather have it do it NOW.
