"Interfaith marriages," Rabbi Lerner says, "are a fact of life." To which I can attest. I'm a Southern Baptist communicant; my beautiful bride is Jewish, and we got married in April 2006.
This is the book we bought to set up our ceremony, and a very helpful and useful book it was. Rabbi Lerner (bless her heart) has been doing interfaith marriages since 1979, according to the book jacket, and she is an unfailing source of help and enlightenment.
I can only speak from my side of the aisle, of course. I'd never been to a Jewish wedding, and all I knew was that you broke a glass at the end of it. I knew a bit more about Christian ceremonies, but I didn't know enough to design a whole ceremony without help.
Rabbi Lerner covers the waterfront, explaining every aspect of the traditional Jewish wedding and the traditional Christian wedding (including denominational differences) and then explaining how the traditions often conflict. For example (I didn't know this) guests stand when the bride walks in at most Christian ceremonies; they don't at Jewish ceremonies. (They sat at ours, but it was mostly because the musicians didn't switch from the processional music to "Here Comes The Bride" for some reason.)
She also includes very nice sample ceremonies that other interfaith couples have used, any of which you can use as a guide for your wedding. Like most people who use the book, we didn't adopt 100% of anyone else's ceremony; we mixed and matched to make up our own, including some very old parts (the blessing over the wine) and some very new parts (the "unity candle", which one of Rabbi Lerner's sources describes as a Hallmark touch.)
Probably the best part of the book is the third part, which is set up as a "menu" - one from Column A, one from Column B. Rabbi Lerner breaks out each of the different elements of the wedding ceremony and gives multiple options for each element, everything from vows to prayers to blessings, with both English and Hebrew given. (And handy transliterations for those of us who can't read Hebrew, although I warn you that you may sound like a goober reading Hebrew in transliteration.)
After that, there are suggested readings from the Scripture and from modern sources -- we ended up going with the traditional "love chapter" from the Corinthian epistles and the ninety-first Psalm.
Anyway, without going to much into the specifics, we had a lovely ceremony, and everyone congratulated us on it when it was over. (And it was short, which I think everyone appreciated as well.) A lot of thanks goes to our officiant, of course, and our families for being understanding, and of course we worked hard on it too. But Rabbi Lerner was a big help, and if you find yourself in a similar situation I cannot recommend her book highly enough.
