The lighting that came with the unit is fine---you can go with mushrooms and various other items....50/50 bulbs are nice.....and you'll have a few watts per gallon. PLACEMENT in the tank is also important. Items needing more light would naturally need to be placed a bit higher in the tank....
See the other thread about the live rock.....maybe you and your parent/someone could meet me at a given time in Bernalillo or something....
I think it would save each of us some $$$$
