Q: How can I export a bunch of files (or an event) from iPhoto to a directory?

1.
   Select a bunch of photos, or select an event that contains the photos
   you want to export.

2.
   File>Export (shift-cmd-E) brings up the Export window.

3.
   Select "Kind: Current" if you've done any editing.
   Select "File Name: Use title" if you've given the pictures names,
   otherwise the camera's file names will be used.
   The "Subfolder Format:" choice is a mystery; I've left it at "Event Name".

4.
   Clice "Web Page" at the top, getting more settings.
   Fill in (or edit) the "Title" item to the directory name you want.

5.
   Go back to the "File Export" page, and click the "Export" button.
   This gets a window that looks a lot like a Finder window, but isn't.
   You can wander around in your directories to find where you want to
   put the files.  You can also use the "New Folder" button to create
   a new subdirectory.

6.
   Then you hit the "OK" button, and it starts creating the files and
   stuffing them into the directory/folder you chose.

There's gotta be something I missed ...
