In a vacuum, the only way to lose heat is by radiation (which occurs very slowly for a relatively cool object like a human body) or by evaporation of fluid. You would still die of course, but it would be by asphyxiation. Your blood holds enough oxygen for about 15 seconds of brain activity.

Do spaceships fly?

The simple act of accelerating something in a particular direction (the rifle bullet or hot gases from a rocket exhaust) creates an equal force acting in the opposite direction (Newton's 3rd law). This reaction is what propels a spaceship upwards or through space, regardless of the presence of ground or atmosphere.
