Your plant is getting excellent light.
Yes, that there is a bulbil and it's ripe for harvest. In my experience they don't root on the stalk, but they do root relatively quickly once removed. Get some fine (nail) scissors and cut the inflorescence below the bulbil. Then trim back the ends of the peduncle to near the base. I would plant in a 4 inch azalea pot, on top of the soil, and water like normal. Once I see growth I up the pot size. Starting small allows me to water like my other plants so I can forget about the situation for a while.
I had a bulbil on this plant (Christmas Carol) that flowered (like yours did) and left a secondary bulbil on the stalk above it. Pretty crazy stuff.
