Wow, I thought you had it running somewhat better. Were all those codes current, or were they pulled up from the fault history?

I still think switching the banks of the crankshaft sensors would be a good, almost free, test that could rule out that problem.

This is all SO similar to problems I had with my G35. Bad grounds actually caused several coil packs to fail. They were melting, and the outer plastic shell distorting. Another quick, (and free,) test that I would do in your shoes is to check the ground straps on the misfiring bank. You know those little ground straps that bolt down to the coil packs in the center of each head? Disconnect each one, and connect a VOM to each in turn, with the other lead of the VOM connected to a good ground, (like the post on the top of the shock tower). Set it to Ohms. You should get NO resistance. If you get resistance, that could mean damage somewhere in that harness that provides power and grounds to the the coil packs and injectors.
