Hmm - I also have almost nothing in the 'Everything else' category under Customise. I have yes/no options for weather updates for home, work and current location. Also an option to select how I get around, currently set to 'Walk'. Nothing else, not even the Temperature units I see in the illustration above.
I know many others are seeing the same as me, and it appears to me that Google Now is a very hit or miss service. People are either seeing the excellent helpful service advertised, or they fall into the other category where a couple of things are working and no amount of coaxing can get any of the other 'cards' to appear. I'm in the UK btw - I've seen references elsewhere that suggest a non-US location could be a possible cause for the problems. If that does turn out to be the main reason for the problems, then the service is seriously stunted.
