Replace the sdd with your USB drive, this will completely wipe the drive. Put the name of whatever iso image you're using instead of the workstation one. The 1024 makes a 1GB overlay. When you boot that drive, any changes you make will be persistent. You can install packages, change configs, whatever you want, up to 1GB of changes. There's also an option to create a home partition as well, optionally encrypted, but you don't need that right now. For now, the /home directory will be part of the overlay.
Done that. I suppose now I need to boot and figure out the changes I need to make.
