@Natrix Spiritual Cloak Gleam Madara never admit it was the first time using the Perfect Susano'o against the Gokage. Tsunade literally said right after he used Perfect Susano'o that she couldn't believe Hashirama fought against Perfect Susano'o (Chapter 589 Page 2). Ohnoki asked Madara why he held back (obviously referring to why he didn't use PS against him and Mu). Madara responded by saying that an adult couldn't fight seriously against a child (never said he didn't have it at that time). Yes, Madara put the armor of the Perfect Susano'o around the Kyuubi. Why would Madara hold back against Hashirama?

Bijuu can be killed. It's just that they will be revived later. It was explained that Ay was going to kill Naruto, thus killing the Kyuubi, and therefore delay the revival of the Kyuubi and delay the Akatsuki's plans.
