no it doesn't power on/off. other than that you get basic controls that a dual shock controller gives you, so not as complete as official PS3 remote.
only one I hear than can pwr on/off is the IR4PS3, but you need to import it from North America and not sure if it works with latest PS3 firmware, you need to check -> check AVforums to research it
