In regards to the hot water freezing faster:
In specific cases this is true. It depends on starting temperature, volume, initial motion... but it does require cooling by rapid evaporation.
The liquid in a straw is not "drawn" up. Your "sucking" creates a pressure zone in your mouth lower than 1atm. So the atmospheric pressure pushes the liquid up the straw. Now you know.
