None.
Calories are a measure of the heat content of objects. If you are referring to the amount of heat radiated by the earth, it would be stated in some unit appropriate to the measure of radiant energy, such as watts or newtons per second.
You may be able to find an answer by visiting the library or using the internet.

Depends on the mass. You can use the escape velocity of the Earth and some nominal mass to calculate the amount of kinetic energy needed to escape the Earth. Then convert to calories.

Actually I think Earth gains weight each year, about 40,000 metric tons per year, due to dust which we pick up as we orbit the Sun.
Anything we burn, eg fossil fuels etc, just stays with us in the atmosphere, although it is thought that some gas (mainly hydrogen) might escape the atmosphere, it would be neglible.
