How to handle the SHU and PC wing

[Sandman]

So I'm having a tough time making a dedicated SHU for my supermax guys. Do you guys find it effective enough to just stagger the regime to try and keep people away, or do you make a designated SHU and then a designated like SNY for your PC guys and other snitches?

Also, what are the mechanics for keeping someone on permanent lockdown? Anyone in lockdown has food brought to them right? Can I still put a shower head in the cell and it will work, or does it actually need to be a dedicated shower zone surrounded by walls with shower time in the regime?

Prisoners will use all the items in their cells. Showers, toilets, pool tables, phones, TVs, Prayer mats and all the rest whenever they need to.
That way you could keep them happy by just stuffing their cells with goods, so they don't get upset but also stay where you want them.
For PCs, I usually construct a tiny-prison of their own, with canteen, common room, library.

Can I keep the guys on lockdown but as long as they have the amenities they will be ok?

Also, do you have to designate every single other shared area to a certain security? Since you can't just exclude securities, what prevents their cell from getting reassigned to another shared tier or them deciding to go to lunch in the shared canteen?

[Frazzledragøn the Trustworthy]

Prisoners will traverse only areas that are of their own security or Shared.
If you don't want them to go somewhere, simply put a "Staff Only" area in between the Supermax and Shared area, so they don't mingle.

If I make a cell Supermax and then staff only in the area around it, where the inmate can't get out of his cell, will he still get food delivered? Or is that only for guys on lockdown and solitary?

Those cells won't be valid, because the prisoners have no place to eat.
I think you can manually assign them anyway, but that's up for you to find out. The last time I tried it was an incredible hassle to deal with cells surrounded by Staff Only. I can't recommend trying.
