The Daled Minim are Muktzeh on Shabbos, so they should be placed in a suitable place beforehand.
Candles must not be waxed into place, nor may the wicks be twisted. When needed, one may remove the wax from the previous night in a way that it falls directly into the bin.
The candles are lit with a pre-existing flame at the usual eighteen minutes before sunset (7:22pm), and certainly not after sunset (7:40pm). The Brocho is recited as per a regular Shabbos.
Since the candles cannot be moved on Shabbos, the candles may be lit in the Sukkah and the husband may move it back into the house after a short while (before Shabbos begins), preferably to a place where they can be seen from the Sukkah. One should ensure that practical benefit is derived from them after nightfall.
It is very common for tables in the Sukkah to be moved around. Therefore, if the Shabbos candles will be remaining in the Sukkah, one should place Challos on the table from candle-lighting until Tzeis Hakochavim (8:08pm), in order to prevent the table becoming a “Bossis”, in which case it can’t be moved from its place on Shabbos.
Pasach Eliyahu is said before Mincha, but not Hoidu.
Since it is Erev Shabbos, one should not eat after sunset – even if one washed for bread beforehand. [One may bentch after sunset and even after Tzeis Hakochavim. In that case, Yaaleh Veyavo and the Horachamon’s of Yom Tov and Sukkos are recited, but not Retzei or the Shabbos Horachamon.]
