This is a great write up!
However,
If you do not own a multimeter the easiest thing to do is install it like common sense would dictate but keep the screws lose.
Start your car and let it warm up to operating temperature (lower radiator hose is hot as upper).
Adjust (aka move) the TPS ****SLOWLY**** and until the idle is where its supposed to be and your done.
This is the ghetto way to do it but if you take your car into my dealership this is how it will get done lol =]

Here is Honda's explanation:
Throttle Position Sensor
Monitoring
The TP (throttle position) sensor connected to the throttle valve shaft is a potentiometer that varies a 5 V reference voltage from the ECM/PCM as the shaft moves. When you use the PGM Tester to monitor the TP sensor, it can display the output as degrees of opening angle, voltage, or a percent of throttle opening, depending on how your Tester is set up. To avoid mixing up your TP sensor readings, use this chart:
Throttle Position
Degrees l Voltage l Percent
Closed (Idle) --- –0.2 l 0.49 l 9.6
Wide Open --- 90 l 4.5 l 90
