Default NB TB on NA and WB Question

I'm finally about to install an MS3Pro PNP on my 95, and I have a few questions.

1) I plan to run an NB TB to clean up the intake. I know I'll have to repin the TPS and IACV. Is there anything I'll need to update in Tuner Studio for TPS or IACV? I believe the IACV frequency is different.

2) I'll be running a Spartan 3 Lite V2 wideband without gauge. I can reuse the existing O2 harness, correct?

Thanks in advance!

Tps - recalibrate
Iacv - retune idle / copy the NB basemap idle valve settings

Got the ECU installed and everything wired up. Looking in Tuner Studio and I just wanted to verify which settings to update as there are a bunch of idle settings. I'm assuming I'll need to update "Idle Control" and "PWM Idle Voltage Comp". Do I need to change any of the closed loop settings? Thanks again!

Any setting related to the idle valve and idle valve duty.
