Sorry but, if you want to stay true by the EULA, you NEED to buy a full version if you don't have a Vista or XP to upgrade from.
As for myself, I don't like to work around stuff I shouldn't worrying about when installing Windows... Also, I don't think an upgrade can be transfered to another PC... like an OEM licence.
My vote goes to the full version.
To OP : You don't need the XP CD at all... just pop the Win7 upgarde disc in... as long as the OS is installed on the hard drive.
