I'm not familiar with lizard litter, but I have a western skink which is quite similar and I keep it on repti-bark. Your set-up sounds pretty good.
You want to make sure you have a good UV flourescent light and lots of cover so that it will feel secure enough to venture out while the light is on (I've read some posts involving Eumeces species that sounded like they were suffering from metabolic bone disease: "what's wrong with my skink?"; the skinks in all these cases were either not being supplemented or had no access to UV or both).
You also want to make sure you gut load and dust its feeders with a high quality calcium and vitamin supplement (this shouldn't be a problem since you probably already have this stuff for your other lizards
). It's also a good idea to have a moist area that the lizard can retreat to to prevent shedding problems. A flat piece of bark etc. that you mist under regularly would work great. You should also provide a shallow water dish, but mist at least once daily in case it doesn't recognize the dish as a water source.
Hope this helps,
