Contact EA Origin support at https://help.ea.com/ with your serial codes - they will add the games and expansions directly to your current Origin account.
If you already have the game installed from disc, you likely already have a Spore account. When you uninstall the disc version, you can choose to leave the Spore saved data in place. If you do this, your saved games and login data will be kept, and will be readable by the Origin version once you install it. You don't need to touch login.prop or any of the other files.
Hi @DarkJamanix

Spore is an older game that does not get redeemed (again) by Origin
Please follow the steps @Kyle_Necrowolf and contact a game advisor
