That's a little complicated, not majorly but certainly not plug-and play if you do that method (effectively involves setting up a small network and configuring up a DHCP server or static addressing) and is not the normal way to use it.
Ordinarily you would use one of two options:
1. Plug the Raspberry Pi (RPI) directly into one of the ports (known as switch ports) on your home router
2. Plug a Wi-Pi 802.11 (Wi-Fi) USB adapter into the RPI, and use this to connect to your home wireless network.
I have a 802.11n usb wireless WiFi connector that came with my package... I don't know if I plug it in and maybe I have to install the drivers on my main PC or if I can just connect through WiFi config on the graphical interfaces' WiFi Config..
The drivers from your PC won't with with the RPI, because the RPI doesn't run x86 code, and the RPI doesn't run Windows (so the drivers would be incompatible).
If you have a Wi-Pi, or if you bought from a supplier who took care with the selecting an appropriate product for the bundle, then you may be able to just plug in the device and not have to install any drivers.
You can then configure from the graphical interface or from the command line.
With the Wi-Pi, there is no need to install any drivers, they are already installed.
After you plug in WiFi on your Raspberry Pi, enter a LSUSB in Terminal to see if it registers. Send back the part for the WiFi which will show chip set on WiFi...
BTW, ethernet cannot plug from Raspberry Pi to PC!
