Will I be able to update my ERAS before they get officially released on October 1st if I get my score between those dates or will I have to notify each school about an update?
Not exactly. Your CAF is locked down at the time of submission, so new publications will need to be communicated directly to programs (keep in mind that nobody but you will really care at that point). But everything else can be changed.
