Well, with shrimps you can't go wrong with silica pool filter sand. Inexpensive, easy to clean & keep clean. Grows plants well using just a few root tab ferts.
The small Fluval CO2 system is not bad and would work just fine in a small tank like yours. It's sort of hi-tech on a small scale. Go for it.
