It's not always possible to simply place raid frames in a "pretty" position, for a healer.
I would put them on the right side ... somewhere reachable for you to click them, or move player and target up and put it in the middle above the actionbars (and above coolline, in your case). If you choose the later, maybe reduce the height per raidmember and/or maybe even remove (or make it vertical to the side of the health bar) the power bar to save even more height.
