I think your ID of the two rooted plants is probably close enough. The floater looks like frogbit. I have a 3g unfiltered tank almost the same as yours, with two aquatic frogs in it, and use the same type and wattage light. I run the lamp 6 hr per day, supplemented by ambient light from a window 8 feet away. I found that when the light was 3 inches from the surface of the water, I got algae. I moved it up to 8-10 inches from the top of the water, and so far, so good, no algae. If the frogbit (?) grows enough to cover the top of the tank, you could move the light a bit closer, to increase the amount of light to the plants below. As long as you don't overstock the tank, a filter is not absolutely necessary, but you will have to do water changes. I sometimes use a portable power filter to clean debris out of my small, unfiltered tanks, before I do my water changes. One filter, for about 12 small unfiltered tanks. Keep us updated with new pics.
Why is the "next" tank, always the most interesting?
