There is no tradition in Judaism of "good luck gifts." The new house is usually dedicated with a new Mezuzah (Deuteronomy ch.6), but the homeowners would most likely want to pick out their own mezuzah, so this would not be a good gift either.
A Mezuzah is a scroll with verses from the Torah hand written on it. They are located on every doorway in a Jewish home except for doors going into washrooms. The mezuzah is a daily reminder and declaration of Jewish faith. Please see the related link for a detailed explanation.
No. There is no such custom. Typically, a completely non-practicing Jew would not even want to use a mezuzah.

The Mezuzah is Mentioned in the Torah so it would make sense that the Mezuzah's been around for as long as the Torah has. Considering the books that refer to the Torah bring you back till the time of the Torah such as Maimonides - 12th century Talmud - 5th century Mishna - 2nd Psalms - 10 BCE That would make the Torah 3322 years old.

In the Torah, God commands the Jewish people to hang mezuzot on their doorposts. Two Torah portions, Shema and Vehaya, include the verse: "And you shall inscribe these words upon the doorposts of your house and upon your gates."The Shema (Deuteronomy 6:4-9) begins with "Hear O Israel, the Lord is our God, the Lord is One." The Shema reminds us that God is always present in our lives, and that we should keep God's words constantly in our minds and in our hearts. The Shema tells us that one way to do this is by writing them on the doorposts of our house. Vehaya (Deuteronomy 11:13-21) assures us of God's compensation if we fulfill his commandments (mitzvot).It is a Torah commandment to hang mezuzot on our doorposts. Mezuzot, in turn, remind of God's presence and of our duty to fulfill God's commandments.
Many cities with large Jewish populations have a street devoted mainly to stores that carry products that religious Jews need, such as holy objects, Kosher food, and items worn when praying (such as prayer shawls). But many non-Jews and also many Jews who are not very religious will shop in Jewish stores if they want to buy Jewish-themed books, Jewish gifts, or if they want to purchase kosher food. In a Jewish marketplace, one would find Jewish food for sale-- if the marketplace is in a predominantly European Jewish neighborhood, the ethnic foods would be different from those eaten in a predominantly Latin-American or African Jewish neighborhood. One would also find religious objects for the home, such as mezuzot (plural of Mezuzah, the object placed on the doorposts of Jewish homes to show respect for God and to remember Him when going into the home and when leaving it), and various kinds of kippot (the little skullcaps that Jewish men, and even a few Jewish women wear in the synagogue). There might be Jewish art for sale, and also Jewish-themed jewelry (some people wear a Jewish star, or a symbol of good luck and long life called the Chai). Whether you are Jewish or not, if you have Jewish friends, and want to purchase a gift for them, you might go to a Jewish marketplace.
