If I remember correctly the 3 pin connector has 1 wire on it which is the rpm detector. You plug that into the system fan header.
The molex on the fan provides power to the fan. It is a pass-thru model so on end will plug into a molex from your psu and the other end can plug into a device that needs molex power. This way the fan doesnt use up a molex connector on you. Yes you can plug the other fan into the first molex (which is plugged into the psu. This is called daisy chaining or stacking.
