Default P1122 ETC plus other codes

My 2004 Nissan Quest 3.5 died while driving about 40mph. It would restart, but die right away. I got it home by trying to race the engine to keep it going, but now every time I try to restart it, it just dies and doesn't stay running. Pressing the accelerator does nothing. I pulled the following codes with my scanner:
P1122 - Electronic Throttle Control Actuator
P1065 - ECM Power Supply Heater
P2138 - Throttle/Pedel POS Sens/Switch D/E Voltage Correction
P1126 - Throttle Control Motor Replay
P1615 - NATS Malfunction

Do all these codes relate to the Electronic Throttle Control Actuator or could there be multiple failures? Should I replace the ETC or does it just need to be cleaned?

Would re-learning the ETB fix it or is this only done after replacing it?

Update: I replaced the Electronic Throttle Control Actuator and did the re-learn procedure and I have the same problem with the following codes. The car will start, but doesn't stay running and accelerator does nothing:
U1000 & U1001
P1122 & P1126 (same as above)
P0605 PCM Read Only Memory
P0444 EVAP Emission Control System Purge Valve Open
P1212 ABS/TCS Communication Line
P1612 NATS Malfunction

I suspect I have a single problem that is causing all the other codes. The battery was faulty last December (under warranty and replaced) and now it won't stay charged, so I'm really beginning to think I have some kind of electrical/ground/harness/short problem. I let the car sit for a couple weeks in January and discovered I had a dead battery when my remote didn't work, so I think something is draining it.
