Well, you need a secure stand that will really protect your instrument, I mean the kind of stand that will lock the neck. Unfortunately, I have not seen a model fitting in a case. But you can also hold it (folded) in your hand while you grab the case handle.
I would not try to pack too many things in a guitar case, like putting songbook between the top and the strings because an important stress on the case could damage the top.
In the tiny compartment under the neck, I have an extra set of strings with a winder including a wire cutter, a tuner, a battery, picks and bottleneck. The guitar strap lies under the headstock.
