TV 3rd Gen accessories

I just got the new Apple TV 3rd Gen and would like to use accessories with it. Can I hookup a keyboard or mouse to the box via bluetooth? Can I use the microusb port on the back to hookup a keyboard or mouse? Also, are there any remotes or other devices that work with this box? The included remote is very nice but I would like one that has more options on it. Any help you can give me would be appreciated. Thanks
