Hi dannybaeh92 and welcome to the grey forum.
All those are great things to know to make your new grey feel comfortable.
The next is up to you, Give your new companion time to settle in to his new home. New home, new people, different sights, every thing will be strange to him.
Sit with him and talk, offer treats, some times just sit by him and read or even sing.
You are going to hear about grey time and that is the time when they are ready to except and trust. Don`t try to rush things, give them that time to make up their own mind.
Good luck with your companion.
