Which version of WordPress are you using? I’m wondering if they changed something in version 3.1 that broke this?
I did try print_r($author) to get similiar results, user_firstname and all the other meta data was completely blank.

Sorry, I thought marking it as resolved meant it closed the topic.. I found a work around and went ahead and just used $author->display_name and $author->nice_name even though having the first and last name would still be preferred.
