You can shoot while sliding and probably also while wallhopping. As long as you use only one hand. I think this goes for melee as well.
Ofcourse, like stated before, you can also stop the animation while performing it, so that you keep control over your character at all times.
Then there's the slide, which will also knock people down if you hit them with it. (I read it somewhere in a Pax hands-on)
