This year (2015 / 5775), the first night of Passover falls on Shabbat (Friday night). Neither my haggadah nor my siddur give much detail explaining how to integrate the two ceremonies. The only statement I found was that on Saturday night, Havdallah is to be combined with the kiddush for the second seder.
What other tips or guidance would be useful to know for this confluence? Is the full Kabbalat Shabbat recited or just the abbreviated one? I assume Maariv should be completed before the seder begins, but should one do the Shabbat kiddush at the end of Maariv like usual, or wait for the kiddush in the middle of the seder? Which wording should one use: the Shabbat kiddush or the festival kiddush? What else am I not thinking of?
