Sarumite, thank you (have you been reading Lord of the Rings?).

I've just two to go and I suspect you have the answers:

1d) Evens out bulk user (4)
B - u -

23a) Collector dropping bits of tin for member of house? (8)
It looks like Aquarian. Is it?
A - u - r - a -

Yes, 23a is AQUARIAN. It's antiquarian dropping the letters of tin. And 1dn is BLUE. Remove the even letters of blue user. It fits in with the theme.
