your residence needs internet access for ONLINE gameplay. you can use a wireless modem with an xbox360 if you buy it.
Yes, any Ethernet cable will work for the 360.
Maybe, depending on what you mean by "phone cable." Those intended for home use probably won't work (the connectors aren't really even compatible), but those meant for 8-pin office phones might work. If you're not sure the cables are compatible, it's probably not a good idea to try it; you could potentially damage your hardware. No ethernet cable are not phone cable and only look the same. The ethernet plugs are larger

Cat 5 is a type or standard of ethernet cable (350 Mhz) and is not as good as the Cat 6 (500+Mhz) which will work wherever you were going to use the Cat 5 ethernet cable and not require replacement as cable/DSL broadband internet speeds increase
The "Ethernet Port" Obviously is used for the Ethernet cable which often connects computers to a router. A router is a device that gets the Internet or from the phone/Internet port and routes it to your computer routers are required for ADSL and ADSL2+ to work. Oftener more than one computer is connected to the router. But this setup may be different for "Cable Internet because i have never had cable.
You need a Ethernet to connect the router to the networking box. All other things (except desktops) do not need a cord to connect to internet.

Any ethernet cable will work. I suggest monoprice.com for cheap cables, but retailers like Bestbuy, or newegg.com might have one.
Yes, it will. This cable is capable of carrying Ethernet information as well, but very few products use this standard at this time.
A phone cord has a different connection. You could make the cord work if you knew the pin-out of an Ethernet cable and the resources to do it but it is much easier to just buy the Ethernet cable.
Make sure you have filters fitted in, for your computer and your phone.
