Nice... Very similar to my approach these days. Not so much the specifics of the workouts, but the underlying philosophy. Although I will probably keep more of a strength focus up though the middle of June. I am using a modified SS program right now and want to give it about three months. As a result, I am limiting my metcon a bit more than you.
Regarding mobility, you might check out Magnificent Mobility. I have been using it for a couple of months now, with good results. I also hear that Eric Cobb's Z-Health program is pretty good, but I have no personal experience with it. Pavel also has some material on mobility, but it is a little pricey for what you get (IMO).
I would suggest that you give the ZMA a try, even while following the sleep recommendation from Lights Out.
As far as explaining what you are doing to others... let me know how that works out for you
