I would say just make him feel accepted. He needs to truly accept who he is and be himself before coming out. When it comes to Christianity and homosexuality, things can get confusing due to all the different interpretations, but I think he'll find many christians if not most will be fine with it; If his parents aren't initially, they will probably come to accept it eventually. If they never do accept him, it's their loss and I guess he has to choose to either be himself without the support of his parents or be who his parents want him to be. It may be a tough choice, but I think there really is only one realistic option.
If he goes to church, tell him to find gay-friendly churches and talk to the priests or other gay christians he finds and see what they have to say. Or you could do this and report back to him :)
As for dating, again meet people at gay-friendly churches or go online.
