Yeah, for uninspectableness (is that even a word?), I'd say either move on to the next trick, or keep a spare, inspectable item on hand. Obviously this doesn't work all the time, but if it's something small like a trick deck/coin, then i always keep a real look-a-like in the same pocket i keep the gaffed version in, so if anyone wants to sneak a peek, I slip it into my pocket and pull out the normal version.
As for people not following directions, I've run into that problem a few times myself. Most people won't do this in a group at the risk of looking like a total jerk, but it's always better to make sure. I always try to create a little plotline for each trick, and use it as an explanation of why they need to follow along.
If a spectator wants to do a riffle shuffle, but your trick depends on a clean cut or overhand, a simple plot can keep them off of the idea. I always stay along the theme of magic energy/chi/mojo, so I say something like "The cards have adjusted to your own personal energy, riffling them together can disturb the balance and might mess up the trick, while overhanding them keeps their energy in clumps, thus keeping the balance between you and them." Using a simple story like this gives the spectator more motivation to follow the rules.
