Routers have nothing related with Windows 8 (an OS).
You need a router not a Windows 2000
That depends entirely on what Operating System the router is running

Yes
Normally, no. The router setup is usually contained within the device itself, so the operating system should not change anything.
The average price range for an 8 port wireless router is $150.00 to $200.00. If the router is purchased online you may also have to pay for the cost of shipping.
There is no Windows 8.
It does not require any particular switch or router you can use either.
Routers are not OS oriented.
Only if my router didn't support any other interface.

There isn't any Windows 7.8, but if you were referring to Windows Phone 7.8, it cannot be updated to Windows Phone 8 (note that I did not say Windows 8 because Windows 8 is for laptops, desktops and some tablets).
