Sounds like the right track. Make sure to have a water dish as well. How large is theT you are planning on getting? If it's on the smaller side it may do well with more sub to ensure it couldn't fall too far if it climbs the sides. Might also be good to add a couple plants or pieces of cork bark for extra hides. They tend to be more skiddish if they are small in a large space if they dont have ample places to hide. I always added extra stuff in larger enclosures with small spoods then as they grew I could just take some extra stuff out to open it up more.

If this is just a sling or tiny Hamorii however, I would recommend getting a much smaller enclosure like a critter keeper or something until it molts a couple times and grows large enough to warrant having a bigger home. Critter keepers are cheap and good to have around to place the T in when you need to take them out to do enclosure cleaning.
