For reference, rebooting a PC is just turning it off and on. What you are planning on doing is a format. Itunes - I don't use this, someone else can help I'm sure. Firefox Bookmarks - go to Bookmarks, Organize bookmarks. Click Import and Backup, Export HTML. That file that is exported will contain all of your bookmarks. A better thing to do would be to use the Foxmarks extension, which automatically backs up all of your bookmarks for you. Up to you if you want to look in to that or not. I use it religiously. For your parents email, you will need to save the email server addresses (POP or IMAP and SMTP). As long as your internet connection is set to Automatically obtain an IP address you should be fine.
