Honestly, I think SU should be left in its Wild West state until it calms down on its own.

For one thing, a dirty little secret of sites like these is that the proliferation of original, diverse, fundamentally useless and nonsensical user-generated content helps the site build credibility with Google; all those goofy-ass "must-have" questions are little pagerank factories. That will help get the site out there and build its audience.

Once the initial expansionary phase has gone on for a while, then I'd say start calming things down and straightening them out. But don't come in with the SWAT team right away.

I would even go so far as to say that serverfault's relative lack of success compared to stackoverflow has a contributing factor in the fact that stackoverflow started out as a Wild West and evolved its social conventions, where serverfault had The Law in place from day one.
