fitler charcoal question

Carbon looses its effectiveness pretty quickly. It can maybe last a few weeks in a unplanted, tannin free, low stock tank. If you fertilize heavy though I wouldn't expect it too last more then a few days. Carbon grabs a lot of stuff out of the water, some bad, some good, most is irrelevant.

so would getting something like this: Tetra Whisper Bio-Bag Cartridges - Filter Media - Fish - PetSmart and not putting the charcoal in work?

As you have a planted tank, I would not waste money on filter cartridges. Buy some filter foam or even floss and cut a piece to fit the compartment. In effect, a sponge filter, which is sufficient with plants.
