My advice:
There's no one of us who is without 'sin' in our lives (and if you think you are, then dig deeper you're in denial). Yet Jesus loves us all. So he needs to work on his personal relationship with Jesus/God and less on his relationship with church ATM. Until he's really come to grips with himself/his sexual identity and his relationship with God while 'living in sin' (like we all do to some extent) I'd suggest he not confront his parents with it.
If he's decent looking, he doesn't need confidence. Just go to any gay club and someone will be hitting on him in moments. If he's fugly or it's a small town with no gay area, then online gay communities, he'll find a ton of support.
