I'm not aware of any computer USB ports that remain powered when the PC is turned off. There are many available AC adapters for USB that would work with any electrical outlet, and these aren't very expensive.
no, not possible, unless you invent something that can make it charge
If your Bluetooth has a USB charger then it can be charged through a laptop computer.
Yes you can when you buy the phone you should get something to plug in to the computer.
You'll have to charge it through your computer or laptop, you should have a cable which will connect you to it.

To charge your ipod touch, just plug one end of the USB cable(ipod should have came with one) into your ipod and the other end into a USB port on your computer. Your computer must be turned on to charge your ipod.
Yes, see page 75 of the reference manual
Do you mean that you are connecting your laptop through a router with your main computer in your home? If so, no there is no additional charge to connect.
no it cannot charge a computer. a phone battery does not have enough power to charge a computer. maybe it can it the phone battery has a bigger capacity than the computer (which is imposibble)
Get the USB to iPod cord and plug it into the computer. It charges through the computer, and if you have a wall adapter, from the wall, too.
Yes it will as power will be put through the usb lead
