While I don't have much to add, I'd like to say, "What excellent advice from everyone."

The only possible thing I could add is that at my mother-in-law's house, it is the custom to sit (in seiza) at the family shrine, ring a bell located in front of it, then put your hands together in front of you (steeple style, not clasped) and offer a short, silent prayer. We do this every time we visit the house (a couple of times a week) to show respect to my wife's father (whose bones are in the shrine).
