Yes all you will need is a thermostat
if you are going to use a divider you need to order 2 fluorescent lights... when you order 1 they mount it in the center of the cage which makes using the divider difficult to impossible...
Other than that looks good.
one last quick thing to note. The T8 is what they call a quick ship item which means that it will be shipped out of their facility in 10 days or less. Their other cages are not quick ship items currently this means that it can take a few weeks (sometimes up to 6-8 weeks) for the cage to arrive. It is certainly worth the wait though.

as long as you keep the layer thin. I have successfully used aspen shavings, cypress mulch, and Eco-Earth (pulverized coconut husk *looks like dirt) in AP cages using just flexwatt successfully as long as I used 1/2" thick or less of them. The thinner the better.
