It might make sense to ask for a lot, going in, so there is room for discussion and compromise. I had a negative experience at last 504 where it seemed the agenda was to remove what were very simple accommodations--so you might have a point.
I also think that it is nice to have a daily report, if it's done in the right spirit of helping the child. When we tried this, at age 8, it seemed like it was used as a vehicle for the teacher to get in all of her jabs and complaints--and it was also very public. I hope your son's teacher is more discrete and helpful.
What I'm doing, currently, is trying to learn more about pragmatic language and being much more concrete and direct with my son re: school and the teacher's attitudes and perceptions. (That has nothing to do with your 504, but just something I wish I'd known a LONG time ago.) I've mostly avoided telling my son things having to do with the teachers' commentary, because so much of it was negative and unhelpful. I'm learning how to translate for my son and wish I'd known about "social communication" issues a long time ago. He is 12--we missed a lot of opportunities.
If homework isn't causing a lot of stress and upset for your DS (and family), then no big deal. It's very overwhelming to have a child who struggles at school and then to have to continue that dynamic at home every night.
When is the meeting?
