Surviving without a spacesuit in space:
Slow decompression will not kill you, 1atm to 0atm difference in pressure is also not that much of a change. The only problems, you would need to protect your respiratory system and continue breathing oxygen, probably by wearing an air tight mask with an oxygen tank. Covering the ears would be another precaution, but I would not know the effects of lack of pressure on them. Another major problem is hypoxia, I do not know if it happens under very slow decompression to 0atm pressure, but if it does happen it can be fatal fairly quickly. As for the temperature, you will burn if you are too close to a sun. As for cold pockets, there are practically no molecules in space, which means you likely still radiate and lose energy very slowly (kinda like a 97 degree sun), but I doubt it would be rapid, like being in ice cold water.
