Each of those shows up as a button on the MMP, so typically you want one for every subject that would interest viewers. Sort of a shortcut for searching. As long as you don't go overboard, I would err on the side of too many rather than too few, because you want to encourage browsing. That said, make sure your categories are well organized and make sense to navigate (things are in the proper subcategories, for example).
