Fish sswim into currents because they expect food. When I do water changes there are several that frequently wim even into the end of the Python where the chlorinated water is coming out (conditioner goes into the tank so the water in the tube is not conditioned). Its a natural instinct to expect food to come past in a current. Also, they have to swim into a current to stay afloat. For angels I would suggest quieter flow.
For light (your plants will not last long-term without an overhead light) on a 5-foot I would get a twin tube T8 (regular) fluorescent fixture. That's what I have on my 5-foot 115g tank. You can mix tubes, and a full spectrum (around 6500K) plus a cool white (slightly higher Kelvin means "cool" or more blue in the colour). That's what I have on my tanks if you check out the photos under "Aquariums" under my name on the left. Does the tank have a hood? If not, a glass cover set (they are not expensive) to cover it, and then the light fixture sits across the frame. I bought two new ones last year to replace old ones that gave out, and I got All Glass fixtures. They seem to be well made, I really like the fixtures. The tubes that come with them are garbage, they went straight to recycling and I bought the afore-mentioned. Sylvania, Phillips, GE all make "daylight" or similar-named tubes, the Kelvin around 6500K is the important thing.
