Wellll, welcome newbie
Nothing that you said in your two posts is a surprise to just about anyone here. Your comments and questions are just about right on track to anyone starting out in poly. Most of us have been there with the same questions and concerns.
I suggest that you do a lot of reading on this forum and elsewhere and get an idea of how others have managed and created their lives. I would suggest starting with a search in the tags to see what interests you. You might want to start with "foundations" and "lessons" and as you seem to be concerned about what to call your self and what is going on then perhaps the tag "descriptions" will help. There is a sticky too on glossary and definitions and book and website recommendations.
It sounds like you have a great start... now its just about educating yourself and keeping on top of what is happening.
