Answer 1

You can do it in your OnComplete method of createUserUsingEmailAndPassowrd().

mAuth.createUserWithEmailAndPassword(email, password)
        .addOnCompleteListener(this, new OnCompleteListener() {
            @Override
            public void onComplete(@NonNull Task task) {

              if (task.isSuccessful()) {
                   //Create your user in DB here

                }
            }
        });
