Yes you will need to appear in person and it wouldn't be considered a renewal it'll be looked at as a new process since the book expired over 5 years ago. You have 5 years from the expiration date listed on the passport to renewal otherwise you'll need to start from the beginning.
No you just go online and apply unless you need to renew asap due to your booking flight other than that you should be fine just follow the process ...
