I'll focus on computer troubles ... no surprise, eh ? ;)
1) I guess short surges are a greater danger to hardware. That's why I have a surge protection for my computer. But I guess brown-outs don't do much good ...
2) I can't really advise anything ... I guess there are a lot of dedicated programs out there, you just have to pick one you're willing to trust. Regarding the medium I'd advise a dedicated harddrive over DVD-R(W) because it's more reliable, and holds enough space so you can schedule automatic backups without worrying about loading a blank disk, but of course it costs a bit more.
BTW, it reminds me of the backup feature in the next MacOs called "time machine" : http://www.apple.com/macosx/leopard/timemachine.html I think it's a great idea, it looks really easy to use and it comes with the system so you just have to plug a backup drive and it does everything in background ... sounds like it will even wake up the computer during the night to do the backup (yes, mac programs can do that ^_^). And I love the startrek-like interface ^__^
