I had a tri level cage for my hammy. I removed the ladder between the bottom level and 2nd level, and attached a spiral ramp, to make it more fun for him. Had his food and water on the bottom level, his wheel on 2nd level, and his house on top level. Had chew toys for him but he really didn't chew on them much. Paper towel and toilet paper rolls are fun for them to destroy. I did feed my hammy Mazuri pellets for hamsters that I found at my local pet store. My hammy has since passed on and I replaced him with two gerbils, who are more active than my hammy was. Now I have them in a 45 gallon tank with mesh top, but I don't think that this environment was as necessary for the hamster. The gerbils really love to dig and make tunnels in the bedding. My hammy was a lot less active and seemed to be fine in his smaller environment. I did have a ball for him to roll around in the house, but do so for only short periods of time, and watch the lids...they have a tendency to become loose and come off when they are rolling around. I lost my guy twice in the house and the cats found him, but they are so mellow they just watched him and left him alone. I learned to put rubber bands around the ball to make sure the lid stayed in place! They are so easy to care for, you won't have any problems.
