I'll be interested to see if any of my American flist have anything to say about 'said'. It sounds very anachronistic to me, but if it is common usage in America, then maybe it's in for a comeback, over here.

I beta for an American who refused a change of gotten to got from me, for exactly the same reason your daughter stated. (That was before I posted about it.)
Interesting example she quotes. What about if she put the contraction into 'I have', so it is 'I've got used to it' or 'I've gotten used to it'?
I'm pretty sure Americans use it in the context of 'They had gotten to the place' as well as 'He had gotten the coffee from the cupboard'. I'm no good at the names of tenses either, but I don't think that is past perfect.

ETA: *points at next comment*
