I feel like Raphael would still show up in camp, just not as quickly as in EA, and the bridge scene is just to ensure it happens.
I'm not sure about one. I didn't notice number one happening, but I've only had the mirror Gale scene show up once in three Act 1 release playthroughs.
As for the second, I believe the game design is that you'll burn through all of your abilities in each encounter, and therefore you'll probably be long resting after 2-3 fights. Problem I've found is that (on normal) I can burn through so much of any given dungeon or location that I don't need to rest and I think going long time between rests leaves things likely to break or be missed.
