There are 2 more mounts at left and right of vehicle and both are major mounting points.
If they are bad, replacing the front and rear mounts would bnot be sufficient to eliminate vibrations. You would most probably be unable to adjust the front mount to sit freely.
I would suggest getting a look at them.
Idling speed is the engine rpm when vehicle is not moving and accelerator is not applied.
