Summary conclusion so far: husband's authority is pre-fall and part of God's design, but it should not limit women's dominion over creation.

A husband's higher degree of authority in relation to his wife is pre-fall and part of God's good design. It should not limit a woman's ability to subdue the earth, have dominion, or invalidate her being made in God's image. But it does inform how husband and wife relate with different authority roles. Post-fall difficulties don't invalidate the harmony of Genesis 2.
