You're going in the right direction. The 2 requirements you need are one to hide the first button when the upgrade for the second research has been completed and one to hide the second button for when the third research has been completed.
Place the requirements in the Ability: Commands - Requirement field for the appropriate ability command and set the Ability: Commands - State to restricted for both.
