By a self-signature. Same for the subkeys (with the difference you already 
noticed that you officially cannot delete the signature).

Sure. You can easily copy "Hauke Laging <mailinglisten at hauke-laging.de>" from 
my "key", add it as UID to your key and sign it. Extracting the original 
signature would not make sense as it would not match the new public key and 
thus not be accepted.
