1. Making the control rod shorter produces more modulator pressure?
Although shortening the control pressure rod does have an incidental effect on modulator pressure, the primary effect of control pressure rod length is on shift points.

2. Mine is shortened all the way and I have no 3rd gear to really speak of, it's shifts way to soon and I have to manually go from S to D to have third gear.
The 722.1xx is a 4-speed transmission that normally starts in 2nd; 1st can be forced by either manually selecting "L", or by the kick-down switch under the throttle pedal. Your statement above suggests that you think the trans is a 3-speed.

3. Which nut do I remove to adjust the screwdriver adjustment to increase pressure?
If an original style vacuum modulator is installed, the banjo bolt that secures the vacuum line to the modulator must be removed to gain access to the screw.

4. Does more pressure stop flairs between shifts?
It often does.

5. What's happening when I have my foot on the accelerator and the engine rpms increase but the transmission doesn't catch up? Does it need more pressure or is it because the trans shifted too early and the tranny doesn't have the pressure in the converter to push?

This transmission does not have any vacuum lines attached. That's why I was asking about the screwdriver adjustment of the modulator
