With newer models it is not important to do, yet if the item is older than it will save Money and energy. Note: If you are going to do this on a gas HW tank be very careful because of the exhaust temperatures (at the top) and the air intake and pilot light and the burners (at the bottom). Good Luck!

It is a thermal jacket that fits over the tank to insulate it
If the hot water tank is off it is possible. It is also possible for the cold water going to the hot water tank to freeze. Insulate all pipes that are exposed - or let them drip (this is more expensive!)
They should insulate their house before they insulate their hot water tanks because if the house might be cold they would want to turn on their heater and heat the house. If their heater is on with the water tank that would take up alot of energy.
No this is not necessary. Install the pipes as per usual. You can insulate the hot water pipes up to two meters or up to two yards from the hot water outlet from the hot water tank to prevent this.

You can insulate it with a higher R factor blanket, but to be honest tank style heaters aren't efficient in the first place, if you want to consider high efficiency water heaters look at some of the options currently available.
Your hot water may run out quickly due to a small water heater tank, high demand for hot water, or sediment buildup in the tank. To improve its longevity, you can insulate the tank, lower the temperature setting, reduce hot water usage, or consider upgrading to a larger tank or a tankless water heater.
There is insulation between the outside and inside wall of a hot water tank. There is also an insulation product that you can get to wrap around the outside of the hot water tank as well. Kit is usually available at any plumbing or hardware store. Only good for electrical HWT, as a gas tank has a flue and the insulation would be a waste on the outside of the gas tank
To insulate the tank from condensation
so then you save more money and so you meet the requirements of the national building code.
Insulation keeps heat from escaping. So if you insulate a water heater, it holds heat better, and does not need to reheat the water as often.

No, a hot water tank heats water by itself.
