Firmware v1.11 is the updated firmware for your camera - it it runs on your K-5. Follow the installation instructions carefully and your K-5 will be updated and your camera will have the new features and improvements v1.11 offers.
The Pentax Digital Camera Utility v 4.33 is software that runs on your PC to help you view, edit, process your JPG and RAW images once they come out of the camera. It updates the version of PDCU that came on a CDROM in the box with your camera.
By all means download and install both. But don't get the installation procedure mixed up
