Root tabs aren't just necessary until the plants take root. They're necessary if you want to provide nutrients to your plants throughout the life of your tank. Typically every 2-3 months you'll have to apply them. However, with a high CEC substrate, you'll likely be able to apply fewer root tabs because the substrate will absorb some nutrients and begin to release them.

Flourite is rather soft, so it should be fine for their barbels.
