What else do I need to do after filling out Form 4868?

What else do I need to do after filling out Form 4868?

1. Do I need to submit it to Massachusetts or is it automatic?
2. Do I still need to file for an extension for FBAR? If so, can I file it myself on https://bsaefiling.fincen.treas.gov/NoRegFBARFiler.html after getting an extension?

Thanks
