I found this page today at the Becket Fund for Religious Liberty (though now, several hours after opening the tab, I don't recall whence I reached it). It looks like a very detailed set of resources about the HHS mandate, including a time-line and many links, etc.
The USCCB's set of resources is also worth keeping handy.
Prayer for the liberty of the Church, from the "Leonine Prayers" after Mass:
God, our refuge and our strength, look down with mercy upon the people
who cry to Thee; and by the intercession of the glorious and immaculate
Virgin Mary, Mother of God, of Saint Joseph her spouse, of the blessed
Apostles Peter and Paul, and of all the saints, in Thy mercy and
goodness hear our prayers for the conversion of sinners, and for the
liberty and exaltation of the Holy Mother the Church. Through the same
Christ Our Lord. Amen.
