If you are comfortable figuring out the wiring yourself, both shields should work with the A-Star 32U4 Micro as a general purpose motor driver, since the Micro provides access to most of the pins available on the Leonardo. If you continue having problems getting it to work, you might post about it on our forum with more details about your setup. By the way, it might be more practical to use our more compact DRV8835 or A4990 carrier board with modules that do not have the common Arduino form factor (like the A-Star 32U4 Micro).
You already quoted our stance and reasoning for it. Whether it's worth the hassle of rewiring your setup to avoid a probably small risk to a $7 part (and maybe your Arduino, depending on which one you're using) is up to you.
The NEMA 17 stepper motor with a 28 cm threaded rod is the only stepper motor with lead screw that we currently carry. We are looking into the efficiency factor you mentioned; do you have examples of places that specify it?
For the animated GIF, we used our DRV8825 Stepper Motor Driver Carrier, High Current. If you are looking for a low-voltage stepper motor driver, you might consider our DRV8834 carrier, which can handle the same amount of current as the DRV8825, but operates from 2.5 V to 10.8 V.
As long as the specifications of your modified bilge pump are similar to those of the bilge pump you linked to, I do not see any obvious reasons why it wouldn't work.
It would depend on which board you are asking about. For a full list of compatible Arduino boards, you might try the Adafruit Shield Compatibility Guide:
