1. Yes replace it. It's your Torque Motor Mount or "dogbone mount." Right now your engine probably rocks when you shift out of park. The part is pretty cheap and takes like 2 mins to replace yourself.
Just support the engine from underneath. Put a peice of wood on a floor jack and place it just under the oil pan. But just support it, there's no need to jack the car up. Unbolt the 2 bolts, replace with the new mount and retighten the bolts, remove the jack and your done.
