The unpredictable encoder behavior was a big enough problem that I had to fix it before continuing. I added 10KΩ pull-up resistors to each pin and powered it back up. All the jittering went away, but I didn't test the pushbutton's stability. Previously, the system registered a clockwise encoder twist at startup, forcing it into the second mode, but this problem also vanished.
My next step was to figure out the accelerometer so that I could activate the mouse features. When I looked up data on my hardware, I discovered that I had a magnetometer, like a digital compass, not an accelerometer. Instead of replacing it with a different unit, like my favorite transducer style, I searched Microcenter and found an in-stock model that talked I2C, so I wouldn't have to change my wiring. I ran the demo program and studied the results, and it should not be a problem to integrate the accelerometer into my hardware.
