Regarding Shaz, he was probably killed by Ichigo. Though it has not been confirmed, he was struck down by Ichigo, who we all know is kind of ridiculously overpowered at times, so unless he had some schrift which allowed him to survive he's likely gone.

Though it doesn't really feel like Kubo would just let a Sternritter disappear without explaining schrift nor epithet...
