I recently bought an external monitor for my MacBook to have a bigger display while I am at home. I realize I can run both screens but usually that is unnecessary for me. My original intention was just to keep the MacBook closed while having it power the external monitor. Someone brought up to me that the MacBook could overheat while closed, potentially causing damage to the screen of the MacBook. Is this something I should be concerned about?

No. This was the case with the iBook which is why clamshell mode was disabled on those. The MacBook is designed to support this so this is available.

The MacBook and the MacBook Pro are both designed to be able to run with their lids closed. There shouldn't be any risk in running your MacBook in this way.

The problem with heat damage relates more to people using iBooks with their lids closed by way of a hack - the iBook dissipates heat through the keyboard and blocking it does pose the potential for damage.

The MacBook however should have no problems running with it's lid closed. Now, if you're going to be doing some heavy duty video encoding I would suggest not only opening the lid but propping it up on something to ensure air flow all around the case. Every little bit helps.
