I do not have an answer for #2, since I don't know the artist, but as for #1 - toss them all! If it's not nice, it won't make you feel good (there's a difference between comfy and crappy, comfy clothes are feel-good clothes, crappy clothes are just... meh, maybe keep one set for painting or other messy work). And feeling good is important! I always feel better when I like my clothes, I can't even wear unflattering/stained things around the house or it brings me down. Plus, yeah, if there's any chance you'd accidentally wear a pair for teaching... toss them!
