upgrade from Vista Home Prem Svc Pk 2 to Windows 7 Professional?

Thank you for all the information that you have supplied.
Just so I am clear about everything I would like to ask: (I am wanting to perform a clean install of Windows 7 and get rid of my old Vista operating system which is on my computer now)
1. Since I am getting rid of Vista and I have the new Windows 7 disks, I do not need to save Vista anywhere do I?
2. After I backup everything that I need from my computer before beginning the installation of Windows 7, do I need to wipe the HD on my computer first before I insert the Windows 7 disk to begin installing Windows 7?
3. Or will the Windows 7 disk automatically wipe my computer's HD as part of the installation process?
4. It sounds like the ideal thing is for Windows 7 to create a single unallocated partition in which case I can click Next and move on to Step 9.
If this does not happen then it will likely create the following instead:
"Disk 0 Partition 1, Recovery 9.9 GB"
"Disk 0 Partition 2, (C:) 139.1 GB"
in which case I can click OK to confirm the selection.
Do I have this right?

As it says in Clean Reinstall - Factory OEM Windows 7 you can make your Vista Recovery disks in case you'd ever want to return it to factory condition, or not. Then I'd get rid of the Vista Recovery partition since it's wasted space.

I specifically explained how to handle the partitions during install in my last post:

During booted install use the Drive Options in Steps 6 and 7 of Clean Install Windows 7
to delete all partitions, then create New as you wish, format and install Win7 to first big partition. Ignore the small 100mb boot partition it creates at the front of the drive.

I successfully installed the Windows 7 software using the clean install process and it went pretty smoothly. I backed up everything. The system installed enough drivers and figured out the Lan settings so I was able to get on the internet right away for updates and downloads. There were not any real problems.
I followed the Clean install Windows 7 and Clean Reinstall Factory OEM directions.
Thanks Greg and Shawn for your help.
