Just a couple of comments:
1. Any disk (except USB sticks) working with Vista or Windows 7 should be formatted in NTFS
2. User data belongs into a seperate data partition. Here is how
you do that.
3. Backup or image your system and your data seperately. That gives you the most flexibility.
4. The built-in Windows backup/restore and imaging functions are not very reliable. I would not use them. Free Macrium is a better choice and much easier to understand. Here is how
to use it.
