Changing one's mind is a slow process, and I did not come to believe women could be ordained without a lot of prayer and study. Check out the introductory books, and then I recommend regular reading on one or more of the websites listed here. And if you really want to dig into Scripture, be sure and follow Dr. Pierce's course on the Theology of Gender.
How I Changed My Mind about Women in Leadership offers 21 vignettes from Christians leaders, some quite well-known, sharing their journey towards affirming women's ordination. Along the way, you will be able to watch them address some of the most common Scriptures and attitudes that tend to stand in the way of women's ability to fulfill the call of God on our lives. See a detailed review here.
Liberating Tradition provides a great introduction to the the whole topic of the place of women in the church. As a Free Methodist elder, Kristina LaCelle-Peterson covers Free Methodist doctrine in the areas of ministry and marriage. This book should be required reading for any pastor who works in a denomination that ordains women. See a detailed review here.
For male leaders, you can read "9 Ridiculously Practical Ways for Male Leaders to Empower Female Leaders in the Church" by J.R. Briggs
