The paralysing light (White Rage Technique) temporarily disabled both Itachi and Sasuke. The only thing that saved them were Itachi's instincts.

Not sure about the effectiveness of sound genjutsu on someone using intangibility. If it works, Obito is dead, if not it's no great loss.

Itachi is the only known user of Izanami. Unless someone else can confirm that Obito knows it.
