You might consider what open/poly models you are and are not up for. Not exhaustive, but a start.
Then these are from the "Opening Up" book.

Reflecting on Change
While not poly per se, you might also think about Non-violent Communication. There are several books, but I like this one best.
Hey, I’m a 33 year old female from Oregon. I’m single & honestly new to the whole dating scene let alone poly relationships. I’m here to get more information about how to start my journey & any advice.
Thank you. I can honestly say that your words ring true with me. “Everyone has advice, everyone thinks they’re right, but nobody has the answers” As somebody who is well established in who I am, I would agree that throughout life everybody/society has advice on how to be but the only person who does know what way of life is best for you is you. Thank you again for your words.For me, the biggest thing I would recommend for people moving into polyamory would be to engage your critical thinking. People will give you lots of advice, and people have been giving you lots of advice your whole life (directly as well as in your ambient environment), and I would say most of that advice is goof-ball.
So I would say, apply your "hang on, does that assertion stand up to reason?" to both the new information coming your way, and to all of the beliefs you are bringing with you. Over the years I have discovered that I have all manner of beliefs that aren't really mine, they just seeped in from my surroundings, and when I apply the "does this stand up?" test they crumble.
