@JasonStone,
I have jetpack and twitter tools for wordpress. And I have hootsuite. My tweets come through just fine, and my blog posts go to twitter. That may be the way to get it done but I think I recall blog posts going directly to FB in addition to twitter.
All of this is for free - I don't think FB has eliminated this as a freebie as it is a way to get decent content in. Understand that the real customers of FB are not its users; it's FB's advertisers. So anything that improves content for them is likely to remain supported, or at least not actively blocked.
If plugin instructions are outdated, you can usually contact the creators of the plugins. If that fails, you can try wordpress's own support forums. I would go through all of that before
FB support.
