I did a little write up of port-security some time ago, covers some of the commands mentioned
Protecting Cisco Switches: Port Security « CCIE or Null!

Your setup is statically configuring the mac address on a port so only that mac address will communicate through the port. If someone else connects a different device with another mac address to that port the traffic will get dropped.

Hope this helps.

Yep there are a few different violation actions. The best violation action will depend on your correct environment.
