Let me know how you get on with your new member. I'm sure they will be fine. I think it is harder though to introduce adults than it is to introduce a kitten. You can buy plug in Feliway. It is a friendly pheromone that cats would give when they rub their faces on furniture when they are being friendly. Feliway has been known to de-stress cats and also stop cats urinatitng on cushions/furniture.
Give it a try and let me know how they get on
