P0122 - Throttle Position (TP) Sensor Circuit Low Voltage
P0123 - Throttle Position (TP) Sensor Circuit High Voltage
without checking it 1st I would guess the TPS is most likely defective.
P0432 - Catalyst System Low Efficiency Bank 2, you may have to replace the Catalytic convertor, it may be worn out,
A WORD OF CAUTION: Don't use aftermarket cats, they tend to reset the same code due to compatibility issues, also replace the cat monitor sensor (looks like an O2 sensor) located just to the rear of the bank 2 cat converter.

P0700 means there is a transmission fault code in the transmission controller. Since the transmission controller doesn't have a light attached, it tells the engine controller to turn the light on using this code. You'll have to access the transmission controller to further diagnose the problem.

Implausible Fuel Volume Signal Received
This usually points to a bad PCM (powertrain control module).
