The X rays are essential in the acute phase both as a baseline for future monitoring of the bone position and to see where the bones are at the moment. This will help the farrier do the right trim and not endanger the foot any more than it already is.
That said though, if the toe is stretched forward at all ,even without Xrays then bevelling the toe back some will reduce the pull from the deep flexor tendon on the bone and help prevent or limit bone rotation. The bevel should be 1/4" in front of where the end of the bone is . In the absence of Xrays, using hoof testers on the sole will easily reveal that line because the horse will be screaming sore right under the edge of the bone. So the practitioner needs to be careful using the hoof testers.
As to the heels, growing more heel is generally considered the wrong thing to do whether dealing with laminitis or not .
However *temporary* WEDGING may be needed in the acute phase to help also reduce the bone rotation even more by reducing the tendon pull even further. But whether to wedge depends on the HORSE and how he is standing and moving in response to the pain. If he is slapping his heels on the ground hard when he tries to walk he does not need any raising of the heels .
But he should have some kind of temporary support taped on or booted on the feet at the first sign of pain or at least at the vet visit. Did the vet do that? If not then you need a new vet who is better informed about the proper first aide for laminitis.
