2- Try to cover empty walls with plastics because it will cost you less as compared to the plywood sheets or try you don't set the generator in an empty shed.

Fumes: It is important to have the ways for fumes because if you are running a generator in the shed, and there is no way out for the fumes, it can cause the issue, so you have to make sure that in your shed you have a small round of vents which can pass out the fumes.  

Also after using the generator you can close the small holes and open them when you will use them.

If you don't have small vents in your shed you can use the muffle-type hose, it will also help you to pass out the fumes from the shed.

Heat: Heatness is the normal process of a generator if you will run the generator for a long time and will power the big appliances then it is normal for the generator, but if you want to cool down it. then you can turn on the fan in the shed somehow it will help the generator to cool down.
