Does anyone have experience with making funeral arrangements?

I’m trying to put together this step-by-step guide for bereaved parents. It is in regards to making funeral arrangements (any and all cultures, at this point it doesn’t matter). I’ve searched and searched on the web but since the funeral home takes care of many matters they don’t list them out. The point of the list is to list all the steps out because bereaved parents sometimes need to know what is going to happen instead of being blindly led through the process. These types of steps can be very helpful.

What I know is you need to:

choose a funeral home, get copies of death certificate, and what else? choose a casket, put an ad in the paper, buy flowers and food, etc?? What is involved?
