Uta Refson's name is actually "Nosferatu" spelled backwards. Nosferatu is a romanian colloquialism associated with vampires or creatures of the night. It was also the title of a German, silent horror film.
The music that plays when Alice and Uta make love is the theme music from Vampyros Lesbos (1971), a notorious erotic horror film from the early 70's, but is probably more recognizable when Quentin Tarantino used it in Jackie Brown (starring one of this show's stars, Pam Grier)
