Aqua fern can mean a variety of things, if you can post a picture (Go to advanced and the paper clip). Anubias is an awesome plant! You don't need special lighting for anubias, but if you want any other plants, get a 6500k plant bulb. Then you would be able to grow many more plants like anacharis, wisteria, water sprite, crypts, rotala, najas/guppy grass, java fern, amazon sword, and ludwigia have all worked well for me or others in low light.
gravel or sand works, but if you want other plants, again, you are going to need at least 20 pounds for a standard 10 gallon tank. Have about 1.5-2 inches in front of the tank and then move to 2-2.5 inches or so. You want to slope the substrate for some added depth and plants need room to spread their roots.
A fert like API Leaf Zone is fine for lowlight, but only get it if you get more plants like the ones I listed.
Stay away from most plants in the tubes, anubias and java fern are fine, the other things tend to be semiaquatic. Mondo grass, ribbon plant, bamboo, and a couple others are not truely aquatic. Stick to the plants I recommended so you have a chnace to have a nice planted tank.
