Personally, I wouldn't do anything until you check the real temperature of the oil with a dipstick thermometer.  A candy thermometer from Amazon with a probe roughly the same length as the bottom of your oil dipstick will do, and for $20 or less you can get a digital one from Amazon.

Bruce had a good suggestion that we can expand upon:  

"Remove your gauge and sending unit and suspend your sender in a pot of boiling water to see if your gauge reads 212 f."

 I would take a slightly different tack:  Remove the sender.  Re-attach the sender wire and add a ground wire from the sender housing to a good ground point on the engine (almost anywhere will do).  

Heat a cup of water in your microwave until it's boiling and then scoot out to the car (don't get any hot water onya!) and place the threaded end of the sender into that cup of water.  (If you're cool you can also put the candy thermometer in there to watch the water temp drop).  Turn on your ignition to activate the gauge and see what it reads (give it a few seconds to stabilize).  

Calibrate your dash gauge with what the candy thermometer tells you or simply note that where the gauge needle is, is probably around 200ยบ F by the time it settles.  THEN you'll know if it is actually getting too hot or not.  Just note where the needle is - It may show 190 when it's really seeing 200.  That difference is important and all you have to remember is the difference and apply it in the future.

While you're messing in the engine bay, make sure there is nothing blocking the fan inlet (John Estes caught a rag in his on a trip to Carlisle one year).
