And she's back on the road! Turns out the damage was minimal. The valve spring sheered and basically collapsed on itself which meant the valve couldn't go all the way into the cylinder so only the valve and the spring were damaged. Both were replaced along with some maintenance items. One VANOS valve, the throttle actuator on that side (other one was already replaced) and the rod bearings. My warranty came through in the end and I would recommend Asurion (mine was with USAA with Asurion as the underwriter). I'll upload and post some pics when I get a chance.
