CAn the data for my Knossos profile be saved and transferred to another computer? My laptop looks to be at death's door and I hope to not have to start everything over if such a thing can be avoided

Someone can double-check me on this, but I think the save data for FSO lives in AppData/Roaming/HardLightProductions/FreeSpaceOpen. Your player file content in data/players would be the most relevant (and maybe fs2_open.ini?), since most of the individual campaign folders there just seem to have log files in them. Knossos itself stores its data in AppData/Roaming/KnossosNET (or just knossos for OG Knossos), but I'm really not sure what would really be necessary there...settings.json maybe? If you want to save all of your installed mods so that Knossos doesn't have to redownload everything again on your new machine, they're saved wherever you told Knossos to install FSO.

I was thinking about my medals and kill lists

As you said in the other thread, the .csg files in your players folder should save your campaign progress, including medals and kill lists. (The wiki says these files have been deprecated and replaced with .cs2, but I'm not sure how new of an FSO version does that; whatever version I have installed still makes .csg files for a new pilot.) You'll also want to back up your main pilot file with the extension .json. If you've changed any control presets, I think those may live in the presets subfolder, so probably best to back that up too. (I don't know if those are a duplicate of what's in your pilot file or their own thing entirely.)
