Answer 1

In 10.6 and later, NSWorkspace has a method launchApplicationAtURL:options:configuration:error: that can be used to pass arguments to the app.

There are also Launch Services functions such as LSOpenItemsWithRole.

You could also send an AppleEvent to the Finder asking it to open something.

EDIT TO ADD: "best" is subjective, but I'd say if you can use NSWorkspace, use it. If you can't, e.g., you need to pass command-line parameters and you need to support Leopard, then use Launch Services.

Answer 2

By using Scripting Bridge, you can use the method activate to launch a cocoa app. See: Scripting Bridge.
