When I built my computer I had a USB 3.0 cord where one side looked like a normal USB to stick into a USB port but the other end has this blue thing:
Where do I stick that in?
This female plug with two rows of ten holes (one hole filled in) on the other end of the USB 3.0 cord

Sure. there's no reason you can't connect the two cable ends. It's probably not worth the effort, though, because you can order this kind of cable online for very little.
USB 3.0 is electrically different from USB 2.0 - it has extra connectors/wires designed in such a way as to gracefully plugged into a USB 2.0 connector - they're located on the 'tongue' where there's nothing on a USB 2.0 connector
As such connecting a USB 3.0 port to a USB 2.0 extension to a USB 3.0 cable will result in usb 2.0 speed, since the extra connectors will not be connected to anything in the USB 2.0 extension cord on either end.

That is a 19 pin USB header connector. The header connector would plug into your motherboard, and then you could add internal USB devices. I have one which I believe is used for a card reader and I think I also had to connect a header to enable a second USB 3.0 port that is built into my case. I'd have to actually look in my case to double check what I used it for.
