I agree that Java Fern, Anubias, and Crypts are going to be your best bets for plants. Java Moss is another one that you could also try. Even these won't grow very fast considering how low your light is.
I really wouldn't worry to much about fertilizers with your current setup. Perhaps dose a good trace fertilizer (Flourish "Comprehensive", Tropica Plant Nutrition, or CSM+B) and some Potassium after each water change. Flourish Excel would get awefully expensive quickly with your size aquarium, so I probably wouldn't bother with it. Fert tabs could be helpful under the Crypts, but not strictly necessary.
