AppFresh seems to show 3 Software Updates that I don't need?

On a freshly installed new MBP running Mac OS X 10.5.4 Build 9E17, AppFresh lists three Software Updates available:
iLife Support 8.2
Java For Mac OS 10.5 Update 1 1.0
Mac OS X Update Combined 10.5.4 (r10)

But outside of AppFresh, running Software Update... shows no updates. Do I need these updates? How do I check what version of these I'm currently running? How do I remove these updates?
 
sad I’m confused
Inappropriate?
