What about trying to do the bt bf lying down maybe in your room? I thought you were trying to get her to bed without nursing?? It's hard to let go of those times isn't it? Could she be getting confused about it?
I think with the night feedings, you just need to be firm and consistent... don't pick her up, just talk to her from beside the crib. It takes at least 4 nights of crying but in the end they are fine. They are not really hungry at those times, it is just what they are used to.
With the time change last week, DD was waking up at 5am again to nurse so we decided to push it back to no earlier than 7am. First night she woke at 5, took an hour to get back to sleep, slept until 8:30, second night she woke at 4am, took about 45 minutes to get back to sleep, and she slept until 7am, third night she slept straight through until 7am. So it really does work! They can understand a lot of what you are telling them at this age.
