Startup (restart) your Mac using a drive other than your usual startup drive as the boot volume. This can include an eDrive created by TechTool Pro, or better, an external FireWire. Make sure that this drive includes a copy of Disk Utility (which can simply be copied from your normal startup volume).
Launch Disk Utility from the temporary startup drive. Perform a "Repair Disk" operation on your normal startup drive (which should now appear as another mounted volume in the Finder)
Again restart, this time booting from your normal startup volume, while holding the "Shift" key to boot in Safe Mode.
Avoid performing any other operations (in Mac OS X or third-party applications) while the update process is occurring.
Make sure all Apple-installed applications and utilities are in their original locations (otherwise can lead to an incomplete update).
Disconnect any FireWire/USB devices before applying Mac OS X 10.4.3, then re-connect the devices one by one after the update process is complete and the system has restarted.
Apply Mac OS X 10.4.3 and restart when prompted, this time without holding the "Shift" key.
Again, repair permissions using Disk Utility.
