Hey all,
I'm currently working through a CEL Code p0171 issue. I've cleaned the MAF sensor, cleaned the throttle body with the (EXPENSIVE) 3M cleaner kit, replaced the spark plugs and wires (spend the money and get yourself NGK P/N BKR5EKB-11 for the plugs), and have now replaced the upstream Oxygen Sensor (actually called the "Air/Fuel Ratio Sensor Toyota P/N 89467-35011)...Still setting off the CEL with p0171 after being reset and is idling rough...
ANYWAY, I'm writing to tell everyone that if you need Oxygen sensors you should just do your research and find the Denso equivalents (as this is what toyota shipped me). You'll save a Sh@t ton of money. Here they are on amazon.com:
Upstream Sensor
Amazon.com: Denso 234-9002 Air and Fuel Sensor: Automotive
Downstream Sensor
Amazon.com: Denso 234-4622 Oxygen Sensor: Automotive
Hope this helps someone (wish I'd known),

Also, in case you want it, the downstream oxygen sensor is Toyota P/N 89465-35580.
