As far as O2 I think you are cutting it way close. I would never jump in with O2 psi under 1000, unless I had the ability for off board plug in (which I do). Just fill your bottles often dive and learn your kit everything else will fall into place.
I think common sense comes into play here. What Setpoint, what depth, duration, etc... Just have to watch the pressure more closely when starting a dive with this kind of volume.
