Seeking Guidance with my OpenHAB2 installation

You need to install the binding for each type of device you want to integrate with OpenHAB in order to communicate with them.

There is no official binding for TP-Link yet, but it looks like there is some working being done. You might check out this thread.

I’ve never heard of Tuya before, but a quick search indicates it is possible to flash the bulbs with custom firmware to enable MQTT support.
