I honestly don't have too much experience with stem plant grouping, but I have to say make sure to use that red plant (Alteranthera sp.?) in picture D.
If I understand your direction, the plant in picture E should be sword plant (Echinodorus sp.). It is hard to scale your aquarium to see its size but from its bright green color it is most likely an Amazon Sword.
Some other things: You will get BBA if the light is too strong and you don't have co2. Another thing is take your time in plant selection (I know its overkill, but I took 4 months on a small 20g).
The night LEDs look really cool btw.
