The problem is a matter of understanding of the Bible, both in what it says (as a whole) and in understanding the time and circumstances it was written in.
Your example about women covering their heads and men having long hair goes (in part) to non-confusion of the genders. The style of hair on men and on women are distinct and different. Even what they wore back then, though very different from what we wear today, the garments for men and the garments for women left no confusion about what gender a person was.
The passage about women not speaking in church was because the women would question their husbands about what was being taught...disrupting the service. The admonition was that they should be silent and ask their questions afterward rather than being a disruption.
Many things in the Bible can be followed literally with significant accuracy, but being totally ignorant of the circumstances and history of Jewish culture and the early Church age leads to misinterpretation.
Biblical rules on master/servant relationships is the foundation for most employment law we have today. It also applies to bankruptcy law. However, that people were used as servants in Biblical times doesn't mean being someone's servant (slave) is a good thing, but when it's done according to God's rules, it isn't a bad thing either...God mandated that a master must be good to his servants...they were people, not just property.
