The sweat absorbs the heat from your skin in order to evaporate.
I'm not 100% sure but i think that sweat will evaporate just like water. The heat of the sun will like... suck it up and it will probably go to the clouds and return as rain.
The body tries to evaporate this sweat and cools down in the process.
It does, that's the entire point of sweating.
It is actually not a matter of sweating more but of it being more difficult to evaporate the sweat. If you are in a dry and windy place it is very simple for sweat to evaporate, in a more humid area there is more water in the air already and therefore makes evaporation of the sweat much more difficult. Then it would appear that you sweat more because you are seeing the sweat, however it is a matter of evaporation.
as apposed to...?
We do not sweat more before rain. However, if rain is coming, there is a good chance that the air is rather humid. In humid air our sweat does not evaporate as quickly, making it more noticeable. To summarize, when it is very humid outside the air is already saturated with water making our sweat evaporate much more slowly.

The sweat glands are more numerous under the arms, and the moisture produced there does not evaporate as quickly as on skin exposed to the air.
The stickiness of the day is humidity. So most of the moisture on your body is the wetness in the air and not just sweat.
You will sweat the same on both days if your activity is the same. It will evaporate faster on a dry day, so you will notice less sweat on a dry day.
indirectly. dark cloths absorb more light and heat and so get warmer which causes you to sweat and evaporate more sweat.
One of our body's mechanisms to cool us down is to sweat. In a low humidity environment the sweat can evaporate, absorbing extra heat from our body to help cool it. In high humidity, it is much more difficult - or impossible - for the sweat to evaporate and thus we can't get the benefit of the evaporative cooling.
