Not only does she owe Emma a lot but except for Rumple, she would be the most useful out of the group. Adam tweeted the original script for that scene.

Mary Margaret wants to help Emma, because she finally opened herself up to love. David is going, because he likes adventure. Regina is helping Emma as a friend, not because she owes her a debt. Also, the babies are with the fairies/nuns.

It is very possible, that no one will be able to use magic down in the Underworld. Which would render Regina, and Gold virtually useless.
