I grew up like that, but the WAKE-UP-ITS-SUNDAY! routine didn't persist through college. Apart from Christmas & Easter for a couple of years, it ended when I left the house. Naturally, I recommend vacating their premises and living in an apartment across town. If only that didn't cost you $40k in student loan debt. Hang in there.
Ah, I don't think it's such a big deal outside of a minor inconvenience. I wouldn't even consider leaving home for the sake of getting away from my family, outside of the fact that it's a part of growing up. Going to church is probably something I could actively refuse and deny (now that I am in college and seen as an adult), but I don't think it's worth the statement of "I want to be away from you". I do remain pissed, however, about the two week church camp when I was still 18, and the church cheering about that tornado. Luckily those aren't going to happen again, or, the church camp won't.Hang in there.
