Driveninsanity,
try a "Good is good enough" approach. Take same time to set the headings, then just write like what you want, do not bother regarding conventions, the flow wil come! Then connect the headings via "connecting phrases" (" the question regarding XXX" will be addressed under the next heading etc.)
Then ask someone to read, be open for suggestions.
Then correct and send! (I know this is very simplified, but you can try it)
Good luck
