Try resetting your custom permalinks to the default setting. If that works, then try reading:
http://codex.wordpress.org/Using_Permalinks
before setting a custom permalink structure back up again.
that link really doesn’t have anything pertaining to my problem. My redirects work when I have permalinks off, but instead go to my custom 404 when they are on.

Which suggests that there’s a problem with your custom permalink structure. Have you tried using one of the other pre-set permalink structures – such as year/month/day/post name?
I’ve tried changing it back and forth… I tried one with dates and it didn’t make a difference.
For example, in my host setting http://www.bloodylexicon.com/vampires.php is supposed to redirect but it doesn’t.

To http://www.bloodylexicon.com/category/monsters/vampires/ presumably, yes? The WP category link works fine. The redirect you’re trying to set up is, I assume, outside of WordPress.
