Well, this works now.

I now have WP cross-posting to LJ semi-decently. However, since I’m still more or less an amateur at php, I could only get it to use the ugly-ass index.php?p=#### links instead of my pretty /archives/YYYY/MM/DD/title-pf-post.php links. This isn’t a huge deal, but I don’t like it. Hopefully I can clear it up later.
