Checking the turn to exploit live players' inability to bet size is a good idea.

As for lead shoving some bluffs, I think it's a viable idea on a Q. I don't think it's good on a spade. As uncertain as I sounded about all of my reads in my post, the shakiness was very real and has a definite effect on his range. His range is really gonna be a lot of 55, maybe some two pair, and maybe some air that's deciding to get weird wid it. It doesn't make sense that he would even have a good draw when he's shaking in the face of a $45 bet.

Not sure if this makes my turn bet even worse, but there were so few nuts that the shakes made sense with that I didn't want to over-rely on that read quite yet. The shakes were completely unmistakable on the $200 raise though.
