It's a 15 pin VGA cable (very common in old and new machines) and USB 2.0 support is spotty in Windows 98 but you can review http://www.usbman.com

But you write... "I want the VGA and DVI inputs for the 2 computer setup "

If you were hoping to hook 2 computers at once to said display, I'll write "it'll never work like this."
