Have you read the "Fats 101" lesson with the breakfast fat task? Here's a screen shot of the portion where Jeff lists nuts.
Above this portion of text in the lesson, Jeff talks about how great coconut oil is, so yes, coconut is a good breakfast fat.
If you search the forum for peanut butter you may find a post from Jeff explaining why he's not a fan (it may also have come up in a later lesson whose sub forum you don't have access to yet).
