The three wells you are referring to are the Affirmed, Assault, and Eastex. Assault is a newer well and I would guess you'll be receiving your interest here shortly (1 or 2 more months judging form the time it took with the Affirmed). Eastex looks like it is waiting to be completed (frac'd) but once it does you'll be receiving a portion of that also.
The Galliant Fox is a permit and I would guess they will get to drilling this sometime this year or early next.
As for what you should be doing you can call MDC with all 4 well names above and ask for updates if you would like to. Other than that I would sit back and think about what to do with my new passive income! :)
