Ill answer some questions for you ^^
CREA: Crea is Ayumi Hamasaki, you sometimes see that name in her CD's, I guess its just her other name ^^
Yes, Ayumi does have a TV show, but she does not make them anymore. It was called "AyuReady?" (There's a link to it's site under the AHS banner.)
Her dolls (figurines) are called "Ayupan". There are many already out.
^^ Hope I could help
(I dunno the other answer about the english titles ><")
