If you are new to making Shabbat, then you may want a guide. One good one is 'Shabbat, 2nd Edition: The Family Guide to Preparing for and Welcoming the Sabbath (The Art of Jewish Living Series)'. It talks with couples, families, groups and individuals about how they incorporate the weekly rituals into their lifestyles. This book has all the prayers in Hebrew, transliteration and English. There's a whole chapter on each! Another good guide is 'An Invitation to Shabbat: A Beginner's Guide to Weekly Celebration', which more compactly steps you through the Kabbalat Shabbat and gives reflections on the day.

If you have young children, I highly recommend 'The Shabbat Book - A Weekly Giude For The Whole Family', which steps you through the weekly parashiot with clay figures. They not only have bite size summaries of the portion, but they have side information related to the parashah.

Last, but nowhere near least are siddurim and a chumash. I've listed them last not because of their place in importance, but because they might be intimidating to someone newly observant. 'Siddur Sim Shalom : a prayerbook for Shabbat, festivals, and weekdays' has the synagogue prayers, but also prayers like the Friday night kiddush, birkat halfvalue (Blessing after meals), and havdalah. The 'The Complete Artscroll Siddur (Artscroll Mesorah Series)' is more complete, but less approachable. 'The Chumash: The Stone Edition (Artscroll Series)' includes not just the Torah readings in English and Hebrew, but commentary and Haftarah readings.
