For the keyboard issue, I think the problem is the Mac99 target uses OHCI. It is a USB controller that implements USB 1.1. Lets try USB 2.0. Could you try this command:
-device ich9-usb-uhci1,id=newusb -device usb-audio,bus=newusb.0 -device usb-keyboard,bus=newusb.0 -device usb-mouse,bus=newusb.0
It adds a usb audio device also. Do you think you could test out a few MP3's if the keyboard works?
