There are examples of women in leadership roles in the early church, so I don't think that was what was prohibited, but rather the word use is prohibiting women from discipling men, which is a specific kind of leadership role. So I think women should be free to have leadership roles, except that women should not disciple men and men should not disciple women.
I think premarital sex is sinful unless the act itself is considered to be a marriage.
I don't hold to theistic evolution, but I don't rule the possibility it out either. It is not important to me to have a firm belief on the matter one way or the other.
As far as the (other) category goes, I hold that we should obey God's Law, but it saddens me when it is controversial that followers of God should follow His commands and follow Messiah's example of obedience to those commands.
