The Windows 7 DVD includes drivers for a surprisingly large number of hardware combinations. Given your chipset, which is similar to mine (see my specs), you should be able to install Windows 7 without the need for the other drivers. Indeed, the only drivers I install are the keyboard/mouse/audio/graphics ones.
If you do decide to install the motherboard drivers, then the correct installation order is as follows: Firstly, Windows 7 itself (and storage drivers, if required). Secondly, any Service Pack(s). Thirdly, motherboard drivers. Fourthly, keyboard/mouse/audio/graphics drivers.
