Yes, all changes are stored.

Yup, the database gets bigger with time because of this.

No, you can always go back to a state before your deletion.

You can however, clean up the database. This is called packing, and can be 
done from the Control Panel/Database Management screen. It removes _all_ 
old revisions of objects up to a certain age. So if you are certain that 
you don't need to roll back to anything older than a month, you pack the 
database to 31 days.

If you really want to remove only one object, you could undo it's 
creation.. Just go to the Undo tab, and check the entry of it's creation, 
and click 'Undo'. This will remove all revision data regarding that object 
from the database. *Warning*: This cannot be undone! You better be sure =).
