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...

What does it mean when the temperature gauge rises while idling then the fan comes on?

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.
