If JSS is choosing to ignore the CoA ruling then isn't that a sign of having a backbone and being stubborn, which is contradictory to your 4th point? It seems when JSS wants to, she will stick to her guns. For instance how many times has the DT asked for the DP to be removed from consideration? A dozen or more. Has JSS caved in? Nope.
JSS can't stop the defense team from "playing games." They have the legal right to introduce motions and they are doing so with wild abandon. The judge has to consider those motions, she can't just trash them and tell the defense no more.
As for the secret witness testimony, there's no reversible error for pissing off the media and spectators and keeping something hidden until the judge is ready to release it. It's not constitutional but then again do we actually know why (or is this more speculation?). I've been wondering if this delay is not so much because of JSS but because it simply takes a long time for the court reporter to complete the court transcript (I know a couple court reporters and it takes longer than you'd think to get it all scoped, proofed, formatted, double-checked, and ready for publishing). It's a very labor intensive process and I've seen it first hand.
