Are any of these good choices?

I took a quick browse in the plant guide at the link below for each of the plants listed in each of the packages offered. Bottom line is, all of these packages offer at least one or more plants that require different light and substrate requirements than the other plants in the same package. The goal is to plant what your existing environment can support or consider upgrading. You may find it more beneficial to purchase specific plants than to go for a plant package.

I don't know anything about your substrate, but from the description you gave of the plants you have, it seems there are some nutrients missing that could be supplemented with a fertilizer. As for light, your light is just over 2.5 watts per gallon or in the low or medium-low range. My advice is to do a little more shopping if you would rather not change your lighting and/or substrate, but are open to adding some fertilizer. I included a link with a chart to help diagnose plant problems you have now.
