Without sounding too critical, You may wish to look again at your plant placement.
Remember that with substrate ferts you dont want to be uprooting plants and moving them once they grow as it will make a huge mess.
Some plant like the twisted Val in the front would be much better suited to the back as it will soon grow larger blocking the view through the tank.
Just a thought.
Regarding the light hood, yes that will be good, but you need to look into the costs of replacement bulbs. I am not sure about the sizes but I know my 2 T5HO units use the 85cm tubes which cost about $60 per tube.
