Hi Bjork,
I'm sorry I missed this thread until now - welcome to Sober Recovery, and welcome to a new way of life. Astro gave you some excellent advice. I believe in open communication, so if you're wondering about these things you asked about, let your sponsor know so that she can begin working the steps with you as soon as possible.
It's a great idea to read the BB, and I found it helpful in early sobriety to attend BB study meetings so that I could get a better grasp of the steps, and how the program worked. I hope this helps. Feel free to continue posting any questions about the program or recovery that may come up, or you are welcome to PM me.
Rowan
