Okay:
here we go:
Edith WAS a Bouvier. She was a BEALE by marriage. It does get tricky, I know. (I've heard people who thought CE was playing Jackie, for pete's sake.)
When her father died, Edith probably got some of the money.
As for the being taken care of there was another man in Edith's life that doesn't come up in the musical: Tom Logan.
He was a musician. But, sticking to the musical: Edie was the one who met Edith's daily needs once she moved back in. Edith depended on her for food, etc.
THe last line you wrote is actually straight from the documentary. (And started a little flame when CE sang it on CBS.) Edie stated the obvious when she said Edith wasn't taken care of sexually: Gould was gay and therefore unable to return the feelings. Tom Logan we don't know about in the musical or anything else. Edith seems to have had a knack for picking up gay men, though.
Edie is protective of her mother, too, I think. This demonstrates that. She loved her mother despite everything that happened.
