About the rear diff lock... crawl under the rear of your car. On the driver's
side of the car (assuming you have a left-hand drive car), on the rear diff, is
the vacuum actuator. It's attached to a lever. See if you can manually unlock
the diff, just to make it easier for you to turn corners for now.
    Been there, done that. Then my diff locks decided to start working again. I
duno why.
