wouldn't it make more sense to get the change of venue decided first, before going ahead with all these other matters?

I would think prosecutorial misconduct would be one of the reasons used for a venue change, if not outright dismissal.

Venue change gets one a new judge, but you're stuck with the prosecutor. The justification for venue change is thatteh proposed venue (judge/jury) would not be impartial finders of fact and law.

Prosecutorial misconduct gets the case thrown out altogether. It is a sword against a renegade prosecutor.
