Start out with minimums on everything except for the CC. After that, I'd channel nearly everything to to student loan, although because I am extremely cautious about things, I might take a look at the numbers and see what it would take at that point to get me back above water on the mortgage. I'd stress about the idea that I couldn't afford to sell my house if something came up and if it was a matter of a manageable number, I'd tackle the mortgage to get it to that point, and then focus on the student loan.
In addition to giving you a little security, this would also allow you to look into a refi if rates are still low at that point, assuming that HARP doesn't work out for you. (I'm assuming you are paying PMI currently so that would be a wash.)
You say you are "100% committed to the MMM lifestyle" but you have 2 car loans, so methinks you aren't as committed as you like to think. Sell both cars and replace with one older, modest vehicle. Even if you can't convince yourself to go down to one car, sell your current cars and buy 2 modest older cars. If you aren't upside down on the cars, ditch them, now.
