Biychidus, I stop after "David Melech Yisrael chai v'qayam"; I would posit that one could stop immediately after making the b'rachah. (Last night, another member of the Ma'ariv minyan, who had stepped outside the shtiebel door while I was in the midst of the b'rachah, was there to receive my SA 3x; and I then waited for him to make the b'rachah and get to that part of the seider in order to respond AS 3x :). Side point: minhag hamaqom in Elizabeth, NJ is to wait 'til 7 full days after the molad before making the b'rachah, so as per Rav EMTeitz's directive two nights ago, I didn't make the b'rachah that [Sunday] night.)
All the best from
