I also need the value of the FB resistors that determine the output voltage since that affects the loop gain.
I don't know the values off the top of my head, that will have to wait till I get home.

I did a quick simulation of your loop and it appears that the phase-shift is 0 degrees where the open loop gain is at least +30dB (normally you want to gain to be no more than -6dB at that point). With that much open loop gain at 0 degrees shift you are pretty much guaranteed a system that will oscillate.
