Good crew will solve your problems
A good sound recordist should be able to keep up with your camera movements, without retricting you. If you are clear about letting them know where you are going before you do each set up. If you do a couple of camera rehearsals, you should be able to sync your movements.
To make sure that the cable doesn't become a trip hazzard, put a camera assistant behind you, to bash (hold and move) the cable for you. S/he can not only make sure that the cable is kept safe, but also watch your back for you, making sure you don't trip with the camera. If you have to move backwards with the camera, get the camera assistant to put one hand in the small of your back to stop you if you are walking into a hazzard (a kerb, a stray pedestrian, a lampost etc).
Just one more camera tip, not really related to sound. If you have your right eye to the eye piece, most people would close their left eye to contentrate on the image through the camera. If you are doing lots of hand held movement, it pays to keep both eyes open. I know this feels a bit weird at first, but you get used to it. Not only does this allow you to watch where you are going, it also allows you to see what is about to come into frame.
