motor mount? I suspect you have a broken motor mount.

An ignition miss would occure at those times. Especially at 50-55 mph, I would suspect secondary ignition components... Plugs, wires, etc...

There are several things that can cause your Jeep to stall while idling. The timing may be off or your fuel filter may be clogged.

Possibly. The main thing it can cause is severe engine wear. Too much oil is just as bad as too little.

Engine temperature rising when the engine is idling is normal. The car is sitting still and no air is entering the engine compartment. This will cause the engine temperature to rise. The cooling fans then come on and the engine returns to a normal temperature. Unless the cooling fans do not bring the temperature down, you have no problems and this is totally normal.
