Aha! The question is finally resolved....bees do just fine on their own WITHOUT us constantly meddling with them! :-D The natural comb looks to be coming along just fine too...be prepared for them to leave a "bee space" at the bottom of the frames until they need a bit more comb.
1) Inspect if you wish, but I saw enough on your video (great job on that by the way) to tell me that she's there and is active. You may want to go in to check for open brood/eggs just for grins.
2) If you're top brood chamber is %70-%80 full, which it looks like you may be, go ahead a pop a super on it and try to catch the later flows. Since you're down this way in FL, I would go with all foundationless (with the exception of a middle frame to get them started straight). It makes for beautiful cut comb and they won't draw it out unless they can cover it...less chance for a hive beetle invasion. Personally, I don't use excluders but if you wish too you should let them draw the wax out before putting one on.
