Aye, I guess at first glance that can look daunting. I work in IT so I'm used to such things. All I could suggest is do it in parts. Split the guide up and do a section at a time, maybe one part each evening. It might look confusing in all it's entirety but once you're in the swing of it, it's all fairly straight forward. The reason for all the parts in that guide is that they're also getting you to backup your system files too, that way if something were to go wrong, you could restore it. But so long as you follow the instructions in order, nothing would go wrong. Once it's all done though, you're laughing. It's really neat having a playlist to select from, with box art and everything and the kids would get used to it in no time.
Anyway, good luck with it all whatever you decide. I'm sure it will all be fine.
