I too use fluval stratum, many LED's are very capable of growing plants - I use LEDs on both my tanks (60g and 6g) and you can see in my 60g that it does grow plants well. Just depends on the type of led. As for the plants, the tall one in the back really makes me think of ludwigia of some sort, I know the foreground plant in the center with the broad green leaves is an anubias and the rest are crypts I think. All of them are primarily low light and since your tank is shallow that light should grow them fine. Anybody else have ideas?
