I'll again suggest that you read here for quite a while before trying to offer much advice. What you've offered up thus far suggests a distinct lack of understanding and even basic experience with relationships, let alone experience with any poly tangles.
Do you even know any polyfolk?
When speaking of various forms of non-monogamy...it ain't poly if you're just fucking around.
While polyamory, open relationships, and swinging are all distinctly different approaches to non-monogamy, they are not mutually exlusive. Folks can, and some do, engage in more than one of them at a time--and it's all good.
