Guys, does anyone know how I update this properly? After following all the steps (before the manual updating and audio fix) my About This Mac window says its Version 10.6. Now when I use automatic software update to get to 10.6.8 my computer has major login issues, hangs, freezes, etc.

How do I manually update? I googled osx 10.6.8 update, downloaded it, but it says you need a minimum of 10.6.7 to do it. So I googled that and it says you need 10.6.6...so the ongoing chain here is not gonna work.
