I haven't read your story but seriously, it depends on you. What is that story to you? How old is it? Is it something that showcases your growth as a writer? Grammar and typos then. Is it an important story, who you would want everyone who comes upon your profile to read? Either option two or three then, but I would encourage you to make that option two. Most of your old readers won't go through the effort of re-reading everything for the extra scenes anyway.
