The basic seven laws are actually “root concepts” of a total life outlook. These are outlined in the many Noachide “guidebooks” that have been published, for example, Path of the Righteous Gentile by Chaim Clorfene and Yaakov Rogalsky. In fact, we just published a new book called Guide for the Noahide by Rabbi Michael Shelomo Bar-Ron. When someone reaches a stage of commitment, there is a standard Noachide pledge -- a public declaration stating belief in One God, recognizing the authority of Torah, and agreeing to uphold the seven laws.
Beyond that, it’s pretty much up to the individual to do what is meaningful to him. For example, I eat cheeseburgers, but not pork or shellfish. I observe a day of rest on Shabbat (certainly not on Sunday, which is a Christian innovation); I don’t work, but I do drive a car. I’ve been learning how to pray in Hebrew, which I feel will get me closer to God. So like I said -- aside from the seven laws, it’s pretty much a personal thing.
The one place we draw the line is that we’re careful not to give a false impression of being Jewish. For me that means I wouldn’t wear a kippah or tzitzit in public, although I am aware of Noachides who do. If I want to put a mezuzah on my door, I would put it on the inside of the doorpost, not the outside facing the street. And of course we are careful not to do anything that smacks of starting a new religion; historically that’s been tried many times before with damaging results.
