From everything I've read, I have a suspicion that the problem is related to your hard drive. KPs when accessing certain portions of your hard drive, KPs when attempting to repair permissions and repair the disk, and KPs when the OS is attempting it's post-boot preen.
So, the problem could be a totally corrupted file system. This is something that DiskWarrior or TechToolPro can help fix. You could also back everything up, reformat the disk (I suggest zeroing out all data), and then reinstalling.
Or, the problem could be with the hard drive itself, which is something you should invest the time to send/bring it to Apple to have your disk replaced.
This is all just my opinion of course..
