Well, yes, but in fact you don't have to do anything at all at the  
server end - they are continuously acting as both master and slave, so  
all you need to do is change where your app points. You can then  
rebuild/fix your other server, let it catch up with the other server's  
binary logs, and you're back where you were with no down time.

Yes. To import it you'd typically do:

mysql -u root -p < mydb.sql

or interactively using \. in the mysql client.
