I've downloaded muCommander and find it better than Finder. When I open folders with QuickSilver it still uses Finder, though. How do I change this behavior?
You cannot change Finder. But you can download a third party file manager and add it to login items: System Preferences - users & groups - login items

launchd to run something else upon login:
You can change the global
Finderby changing the

Finderby placing a modified plist in
Be sure to read the entire thing for warnings. It sounds like a risky idea.
If that doesn't work, QuickSilver might be hard-wired to launch Finder. In that case, you will have to contact its developers and ask them for a new setting.
(Note that things like the File > Open dialog will still use Finder, since that is part of the operating system.)
