Event header formatting - Eliminate author, move attend buttons

Two questions on the event header.
1) Is there a way to hide the Event Author WP Name? I didn't see that option and I think most of our users won't care who authored it. Save some space this way.
2) The attending buttons are right justified, at least in my implementation, so on a larger screen they are to the right and may be easy to miss. Any way to adjust that?
Thanks so much!
