Anyone else having a mad Yuri Day party?

Finally, how long before these people get sued for BLATANT copyright infringment, as these things are apparenly being sold?

Short answer: Never. Doujin [generally knock-off mangas with licensed characters, often adult in nature] are huge in Japan. Comicons there are absolutely FILLED with the stuff. Apparently, Japanese companies don't mind them because they act as free advertisement and the fact that they are usually published in very small quantities. Just don't try that in America.

Question! Did you scan those strange book covers or did you just fine those images online?

They were most likely found online as there are hundreds [thousands, maybe] of site dedicated to doujin.
