I don't think that turning off the tv or oven really has much effect. It is still plugged in. If you don't unplug them (and I wouldn't go near the plug during a storm) you might as well leave them on if you want. I imagine that surge protectors could help but probably not in a direct strike. I think they are more for surges in the line voltage. I don't think there is any more danger to your person through a tv or other appliance as long as you are not touching them of course!
