Well, I guess Wanda’s ghostly form will simply merge with her new body/self.
As for the rest, on how big a part Krakoa is playing in this remains to be scene. I think Krakoa still has Tommy and Kyle.
I do think Wanda accidentally summoned or formed those monsters when they interrogated her. This Wanda is pre Avengers disassembled but from the time period where she had major power gains due to mastering chaos magic.
