PC on a few items

I'd appreciate any help you guys could give me, (including "drag them all to the trash bin in the Inventory panel"). I've just started looking into the trading activities, and I have to admit am utterly confused on what's worth what.

These are all items I've found hunting. Haven't applied any mods to any of them... yet... not sure if I should, or if it won't help at all, for better or for worse.

Thanks in advance for your time and help
