Right now, consider that you are given a pass on any practice such as fasting or any particular prayer unless the priest has told you what to do. If you are curious about a practice and want to give it a try, ask the priest about it.
It would be best to have a regular time to talk to him, or ask when he would prefer you to contact him with such things. He may well say "anytime", but at least you will have asked. Your journey into the faith is a long one.
Even after Baptizm/Chrismation, you will continue to learn and struggle and grow. That is the nature of Orthodoxy. Even a very old Abbot of a monastery will tell you that he is learning how to be a Christian every day. The official "stages" are not as important as what you learn along the way.
I felt extremely at home right away, and the priest felt that we had met somewhere before, though we had not. I went to church at there for about a seven or eight months as an "inquirer", because I had a lot on my plate stress-wise and couldn't give good concentration to catechism. One day after a heartfelt conversation with the Fr. Constantine, he gave me an olive wood cross on a string (a necklace) that was from Jerusalem. He said, "you are now a catechumen...we will formalize it in the future, but for now wear this and pray the Lord's prayer three times a day."
I ended up moving abruptly a few weeks later due to business related problems. I spent the next year and a half visiting a few churches in my area, including settling in as an inquirer/stealth catechumen (as I hadn't discussed the previous situation with my new priest) for a good six months. I finally told Fr Vasile about the previous conversation with Fr Constantine, and that I was ready to actively resume my move toward coming into communion. I felt very Orthodox by that time in my self identity, and that what was left was to "formalize" my learning and come into communion with the Church. I spent about two and a half months, starting a month or so before lent, in very rigorous reading and discussions with Fr Vasile. He prayed the Order of Exorcism (often done just before baptism/chrismation) over me on the first weekend of Lent, and then I was Baptized/Chrismated on Holy Saturday just over a year ago. So it can be a very twisted path, but I never felt pressured to move faster or slower, but to move with the haste which was just right for me. I think that this is how it usually is. As to your husband, I would tell you to continue to love him and be with him, but to also work out your own salvation. I suspect he will be impressed by the serenity he will see growing in you. I said in another thread to heed the advice of St Seraphim of Sarov, "Acquire a peaceful spirit, and around you thousands will be saved."
Wishing you peace, blessings, and many years.
