Does anyone know how to get in contact with IronRealms directly through e-mail? Looked around the site, but can't find a single e-mail address that doesn't go to the various games...

It depends on what you need. They have media relations, individual e-mails for the head honchos, whatever. If you're looking to send a resume, be sure to put something about Viagra in the subject line to help the poor guys sort it faster. Matt Mihaly has mentioned a few times that he gets multiple unsolicited resumes to both IRE and Sparkplay daily.
