No, this usually means that the user hasn't changed any settings yet.  
There are a few preference exceptions from this rule that are saved  
automatically without user interaction.

No, but only of the preference value has not been saved for the user.

No, changed preferences are saved at the end of the request. They are  
cached in the user's session though, so changing preferences on the  
server doesn't have any effect until the user logs in again.
