No, this does not change anything about the public key.

Yes, that adds new signatures to the key that need to be uploaded for
new expiration dates to be seen by other people.

This depends on the keyserver implementation.  Generally, the new key
gets merged into the old one.  Sometimes the stale data is cleaned up,
sometimes it remains.  The same happens when you fetch updated key
from the keyserver.
