Kabbolas Shabbos begins with Mizmor L’Dovid, and not with L’chu Neranenah. In Lecho Dodi, we say B’Simcha U’vetzahala. The Shmoneh Esrei is the usual one for Shabbos, with Ya’aleh Veyavo added. After Shmoneh Esrei, the Shabbos selections are recited – Vayechulu, the Brocho of Me’ein Sheva and Mizmor L’Dovid.
The custom of avoiding Kiddush between the sixth and seventh hour on Friday night applies even when it falls on Sukkos.
Shalom Aleichem and Eishes Chayil (as well as all the other selections prior to Kiddush) are recited in an undertone.
Kiddush is recited as on a regular Shabbos, with Leishev Basukkah added at the end.
It is customary to use the Challah of the Eruv Tavshilin as part of the Lechem Mishnah of both the night and day meals. If possible, it should be eaten at the last meal of the day.
It would appear that Azamer Bishvachin is not recited, even though it is Friday night. The householder leads the Mezuman, as it is Friday night.
In bentching, both Retzei and Ya’aleh Veyavo are recited, as well as both the Horachamon for Shabbos and Sukkos.
At Shacharis, the Shmoneh Esrei is the usual one for Shabbos, with Ya’aleh Veyavo added.
Hallel is recited (see section “Hallel” on second day for relevant Halachos), but not Hosha’anos.
Before Musaf, Yekum Purkan is recited as per a regular Shabbos. All the additional Shabbos selections are recited in the Musaf of Sholosh Regolim. If one did not make any mention of Shabbos in the middle Brocho, or if he mistakenly davened the regular Musaf of Shabbos: If he did not yet say the second Yih’yu L’ratzon (at the end of the passage of Elokai N’tzor), he should return to the beginning of the middle Brocho (i.e. Atoh Vechartonu). Otherwise, he must repeat Musaf.
The paragraph Vlakachta Soiles is recited before the Shesh Zechiros.
For the daytime Kiddush, everything prior to Kiddush is recited in an undertone. One should remember to recite Leishev Basukkah before drinking the wine.
Shabbos ends at 8:23pm. Vihi Noam and V’atah Kaddosh are not recited on Motzei Shabbos.
Havdallah is recited as on every Motzei Shabbos (with Besomim and candles), followed by Leishev Basukkah. V’Yiten Lecha is recited in an undertone. A Melave Malka meal is conducted, as per every Motzei Shabbos.
