Use the drivers given by the Win7 installer, and then quickly updated via optional Windows Updates. I would not change them unless there is a performance reason or a driver is missing in Device manager.
Enable hardware driver updating after install, as well: Automatically get recommended drivers and updates for your hardware
Tips for gettting a purrfect install based on hundreds done here: re-install windows 7
I agree with everything said here about BIOS updates however from my experience updating from Windows is actually a safer method than flashing from stick or disk.
