nVidia Shield TV has full USB mouse/trackpad support, alongside keyboard. I plug in a Logitech K400 Keyboard+Trackpad RF mouse into my Shield and can navigate using the touchpad with no problems (a mouse pointer appears when you use a mouse/touchpad). I've also used Bluetooth keyboards and mice. I've not sideloaded a browser but see no reason why it wouldn't work effectively.
