I have only been using TightVNCServer for a while now. Is there a way to bypass this?
Only if you use RealVNC server and viewer. It has a feature to capture the video that bypasses the framebuffer (such as the pi camera preview)

Re: How do you delete the "work" directories after a build?

I am unable to due to privileges. You need admin privileges; use 'sudo' From the command line use e.g. sudo rm -rf name-of-the-directory This will recursively remove the content of that directory. Be careful when you use this; it's easy to delete something that is essential for keeping the Pi running

Did you double / triple check that you followed these exactly?
Any odd / error messages?

Re: Camera won't preview

Are you using a monitor directly connected to the Pi or o you use remote access software (VNC)? By default the preview only shows up on a local screen. What command did you try? Did you check out the raspistill / raspivid documentation? https://www.raspberrypi.org/documentation/usage/camera/raspicam...

Re: Difference between these 3.5" HDMI displays?

I suspect the first listing is fake, and believe the resolution is misleading. The cable you mention is to power the backlight and interface with the screen and touch controller. The second screen you showed is the same thing, fake. The resolution of screens this size and price, is not going to be ...

Not possible, it's for a different processor architecture.
