welcome to the forum! I was Presbyterian before I was Orthodox. I recommend going to your closest Orthodox Church and speaing to the priest about "inquirers classes". they had these classes when I was first interested in the Church. it would be good for you to attend Divine Liturgy, to get a taste of Eastern Worship.....it's the most interesting experience in the world. Parishes, for the most part, offer a small Parish library or bookstore. you need all you can get, to find out about it.
good luck and God be with you on your journey!
