The FN's are great cages. There is a whole thread devoted to FN cage set up's you should check it out to see what Smokey needs for his cage. You need to get rid of the ramps because his feet can get caught and then his could get a broken leg. You'll also want to get the Bass Equipment pan or pans for the cage to hold the shavings or fleece liner.
Also the best thing for chinchillas is a water bottle and not a water bowl. With a bowl they can jump in it or tip it over and get wet which could then cause fungus which is not good for chins.
