Be natural as good friends. You also need to have good table manner, help up with the cleaning of dishes (if you invited to eat together). Keep the room, floor and and everthing tidy. Offer to help whever possible.
First of all, that is awesome that you care. I would just say that you should act the same way you would want anyone to act in your home. And also, if you are very uncomfortable, they will be too, so try to relax.
The normal stuff. Wear decent clothes, bring along gifts for them. And wish them a happy marriage.
