See....I heard channels can conflict if each USB port doesn't have its own "controller". 
Unfortunately...I have no idea what that means.
Hence why I figured perhaps a PCIe to USB card would be more beneficial. 
(Info based on what I saw when Linus from LTT tried to set up his full body for beatsaber streaming)

As for the advanced settings. I know it's not NEEDED. But I've heard from other players that it does help with accurate tracking.
Was just wondering if one program did it more efficiently than any others.

 Play-space moving and adjusting since some avatars are crazy short/tall. 
Supposed to help with accurate tracking so arms/feet and body aren't the wrong size

2.
I'll start checking out some Hubs and compare them to the USB cards. Try and weigh my options here. 

3. 
I don't follow

I've got desk space and such to spare.
Plus I'm usually decent at routing my wires and keeping things neat and clean looking
