Switch to high bar or take a wider thumbless grip for lowbar if your elbow is causing issues. It really does not matter whether you do high bar or low bar at this stage (or any stage? probably.)
For press I've had the same problem. It gradually got better without the need to do unilateral accessory work. I think it might have been more of an imbalance in mobility from shoulder to shoulder than of strength. No way to know for sure but I think adjusting my sleep position helped that a good bit; specifically, never sleeping on my left side on top of my left arm. I try to remember to flex my shoulders before I sleep and it's like a passive stretch all night long. (
shoulder extension/flexion) Again, no idea if it helped but it seemed to!
