1-4. Preventing events from Gmail from appearing 

By default, Google Calendar is integrated with Gmail, which may cause information from received emails to be automatically added to your calendar. (When synced with Garoon, these events are synchronized as "Private" information.) Because of this, flight or hotel reservations and other details from emails sent to secondary groups (mailing lists) may be added to your calendar even if they are not relevant to you.
