1. Depends on how many modules are being heated, what your Therm skill is at, whether you've got a heat-sink mod, etc.. If you overheat something in EFT using r-click, you'll get a timer to the right of the mod for an idea of how long.
2. Yeah, but bear in mind your other mods will still take damage.
(b) I know nothing of paste and would like to learn all I can.

3. Not really too bad. Repairing my megas whole high rack from severe damage usually costs me around half a mil or more.
4. Yup
5. You can turn heat off individual mods and they'll stop overheating after a cycle, yes, but it's important to note that they'll still take damage from any heated mods around them.
Hope that helped/wasn't terribly wrong.
