I wouldn't use a sump with a planted tank, there is no need for it, and the sump allows a lot of CO2 te escape. you don't want that, your plants won't like that. Go with a cannister.
Regarding lightning i couln't say for shure, it kinda depends on the frequenties the bulbs are emitting, but 13000K is a bit to much imho. That is real reef stuff. tha highest I get is A 6,5K lamp that would be better, but the 4k type is used here a lot above planted tanks (Philips 840 TL).
A fluidised sand filter on a freshwater tank is not a bad idea, that type of filter dont eat a lot of NO3 what is one of the things your plants need badly :-)
