Great questions. My first thoughts are: go ahead and proceed with what has been given already. What file are you linking exactly for reference @hadiczech ?
Keep your own files local to your Computer/etc. for now.
Yes get right to work. Keep it fluid enough that you can roll with changes on the fly. You are welcome to work it out with @jakeblended or trudge along and make changes. With so many hands in the cookie jar you just gotta dive in and grab a cookie.
