My 2 cents on the guy getting the degree:
Any number of famous scientists have believed any number of ridiculous things (I'm not calling belief in God ridiculous at this moment). Newton was an alchemist, for instance. There are people publishing books on UFOs outside of their research into astronomy, many physicists starred in the "documentary" what the bleep do we know, hell, extend it far enough and you get chomsky and dawkins who publish social commentary. What people believe and do in their spare time is unrelated to their science.
Add to that, so long as he maintains a certain level of quality, what is the danger of him, outside of the auspices of a scientist, supporting young earth creationism? For the scientific community, I feel this would be beneficial. My initial thought is that this guy will come at evolutionary sciences with a much different perspective, and so long as the methods are good, will offer new and untried interpretations that, at the very least, will start new avenues of research even if they turn out to be wrong.
The very worst I see is him becoming someone like Behe, who does highly questionable scientific work (at times, calling a spade a spade, he is somewhat reputable) yet has certainly forwarded out understanding of something like the bacterial flagellum. The amount of research into the evolution of a flagellum, imho, is directly related to it being used as a crux in intelligent design arguments.
About the Smithsonian article:
If, and this is a big if imho, the article which promoted intelligent design was of high enough quality to be published in a biological journal, I see no reason why not to. At the end of the day, the editor should have the final say about what is in his journal, but I've seen 4 or 5 article debates in journals about far less interesting things. Again, as above, the worst thing that I think can happen is that research into why the researcher may have been incorrect is started.
