Ghost shrimp EAT cherries, just so you know.
No, you don't need co2. Shrimp don't like it anyway, and it sometimes kills them if they get too much.
You don't need uv light for shrimp. Just enough lighting to grow their plants. Low-med light is good for a shrimp tank. Good plants- moss, crypts, elodea, various stem plants, floaters, etc.
I use a fugeray led on my 29 gallon shrimp tank. It works pretty well, but there are many other options. A daylight cfl would be fine too.
Tops are convient to reduce evaporation and shrimp escapes, but not everyone uses them. They do reduce maintanince a lot though.
