Please forget any method you used for Windows. Linux (and thus Ubuntu) is a complete other ballgame.
Linux uses generic drivers. This means that IF hardware is supported by Linux the drivers are included with the system and during installation Linux will install those drivers for you.
For the motherboard you need no drivers. That Utility DVD you have is worthless when using Linux. Unless there are documents on there (but the drivers and software are useless).
For graphics cards we have native drivers but also drivers from the videocard manufacturers. Linux/Ubuntu will install the native driver and after installing show you drivers it has in its arsenal that are provided by 3rd party manufacturers. System settings -> software sources -> additional drivers:
The wireless card. Here: http://linuxwireless.org/en/users/Devices/USB it says
rt2800usb Tenda W311U 0x148f 0x3070 (I assume this is the one you have too since it is not listed elsewhere) and the driver rt2800usb is listed here as supported: http://linuxwireless.org/en/users/Drivers In the past you might have needed to install the windows drivers with a program called ndiswrapper but this is getting rarer and rarer!
