My LJ Crossposter plugin (http://wordpress.org/extend/plugins/lj-xp/) for WordPress should work equally well with Dreamwidth. I confess I have not tried it. Assuming that part works, I would set it up like this:
WordPress to Dreamwidth using LJ-XP Dreamwidth to LJ using DW's built-in crossposting tools (http://www.dreamwidth.org/support/faqbrowse?faqid=98) WordPress to Twitter and Facebook using Jetpack (http://wordpress.org/extend/plugins/jetpack/) (the most reliable plugin I have found to handle both at once)
If LJ-XP does not work with Dreamwidth, let me know and I'll see if I can fix it.
