John,
It sounds like your chakras in your hands and feet were opened. Sometimes the attunements will focus on opening the crown chakra.
You would not combine Reiki with qigong so you should just use them separately. You usually don't get the symbols until the 2nd and 3rd attunements.
Qigong alone is adequate but some people are drawn to explore the broad energy matrix. Since you're into free attunements and they can be easily obtained through the web, why not add the Universal Energy Healing modality to your energy toolbox as well? It's different from Reiki, qigong, and pranic healing.
