Hello RichardHooker,
From what others have stated, yes, I think your biggest hurdle isn't your GPA, but your being from Liberty (as justified or unjustified as that may be). I'm pretty familiar with Liberty, their Phil head was a PhD in my department (I read his dissertation last year in a seminar on the Problem of Evil), my younger sister attends there, and my father is a D.Div. alum from there (and about the arminianism--that surprises me quite a bit. From my understandings the vast majority of theology professors there are calvinist dispensationalist, like Dallas but even more conservative).
Being "conservative Anglican", and interested in Philosophical Theology (what I am also going into, though I am more interested in the academic arena), I would recommend Yale Divinity, if you can get in with some funding. Like others have stated above--divinity schools are way easier to get into than good philosophy MA programs, especially good MA programs (like Miami's competitive funded program). Also, if you want to move on from there, having a more broadly accepted name on your CV will help as well. Paul Griffiths at Duke is incredible, but he is a mildly conservative (yet post Vat II) Catholic--pick up his Apology for Apologetics to pick up how serious he is about some issues.
One issue you might have is that Yale's program is more considered "analytic" than not, especially with John Hare heading the Philosophical Theology programs (in both the Divinity school and Religion & Philosophy programs)--but I don't know where your philosophical inclinations lie on that scale.
Are you thinking of Calvin or TEDS? They have some great scholars on the conservative side who do some philosophical theology.
