I have had this issue before. To be honest the quickest way to get around this is grab a wireless or wired keyboard and mouse, plug it in. Windows will find the usb keyboard and mouse, like a logitech and you can continue with Andre's comments.
You need to run bootcamp on the mac side and make a windows drivers usb. I find it odd you have no keyboard, its usually the trackpad that is the PITA.
Good luck.
