If you have made backups of all critical data, the easiest would be to just start the Windows 7 installation and let it format the drive.

You can not upgrade a 32 bit OS to a 64 bit. You must do a clean install.

Back up your files that you need to keep and boot to the Windows 7 X64 bit DVD and install.
