The ideal way to do this, in my opinion, is by configuring the redirects in IIS.  There are third-party modules to do it, I'm not familiar with any of them (I am quite familiar with third-party modules to redirect users based on role assignments or other properties but that's a different kind of redirect altogether).

You can create a new virtual directory.  At first, if you're using the wizard, you'll need to specify a home directory.  Do that, then after creating the new virtual directory, go into its properties.  Change it to "A redirection to a URL" and then select from the options which appear after making that choice.  Mark it as a permanent redirection if you want search engines, etc. to update their indices.  I usually leave them up for a few months after doing a search engine submission, after migrating a site over, then I remove the virtual directories.  One of the nice things about the virtual directories is that you can more easily track them separately in the IIS logs so you can monitor when the traffic has died down, plus of course you can simply search for the old URL in the major search engines and see if it has been updated.
