Iaq thermostat and upgrade with uv

[Hivoltage98]

Hi all, first off thanks in advance, I'm an electrician and work with controls but need advice on the proper way to set up my system RIGHT.
Here my current setup.
A/S 2 stage with variable speed blower (always running it for balance)
Aprilaire 700 humidifier
Aprilaire 5000 EAC
Aprilaire ventilation damper
Future uv light

I purchased a honeywell visionpro iaq thermostat and want this to control everything now.

Question 1: should I just remove the controls that the hum and fresh air damper have? I think it's a yes but didn't know if there's anything I'm missing

Question 2: can I set this up so when fresh air or humidifier call to run it speeds up the blower?

Question 3: UV lights, what are your thoughts, I hear so many conflicting
thoughts on them, proper placement, how many, what size, I want to do it right and not have a useless glow light to waste electricity.

Question 4: proper placement of a discharge air sensor? How far downstream is most advantageous?

I also intend to put an outdoor temp sensor and indoor temp sensor and discharge air sensor.

Thanks
