I usually (yes, sadly, opening up the doors on the x5 is a fairly regular thing for me, even though everything I fix stays fixed and I do what I can to fix things before they break) disconnect the battery first to reduce the chances of the airbag going off when I remove it. But then I usually find it convenient to restore power so I can adjust the window during the rest of the repair.
Re-connecting the battery with the airbag module removed will set the airbag light on your instrument panel.
But since I had that light on when I bought the car, one of my first purchases was a reset tool. If you don't have such a tool, you would probably want to avoid having the airbag module removed when the battery is connected.
Regarding cutting cables, no I would not do that. I also would not take it to the fire dept so they can practice with the jaws of life. But that's just me. I usually prefer to fix things with minimal destruction.
