Hi. I'm not a relative newbie to the boards and I have some of the same questions. You've written more in this one story more than I have total.
I agree with LadyTpower. It sounds like you need someone to Beta read your story. You should have enough for someone to get the gist and make suggestions or ask questions to get you thinking about how to bridge the gaps. I'm not sure where the lines are between Beta reading, brainstorming and coauthoring but I'm sure there's overlap wherever it is.
