Regardless, I think you could probably use some kind of cloning software. I do it how I list above though so I have no experience of that. Maybe someone who has will chip in now.
You do know that you could do what I say above and retain your apps and settings (not OS updates but that's like 10 minutes of DL time) by copying back your Library (in home directory) and your Applications directory to the freash OS install?
If you have a firewire enclosure that you can temporarily install the new drive in you could use "Carbon Copy Cloner". it works well, and is free. To get CCC simply search the web, I use Google, for "Carbon Copy Cloner".
