1. What exact steps tell my blue to boot from microSD?

As a default, I've provided the answer via a FAQ.

2. What steps tell my blue to boot from onboard memory?

Blue boots from on-board flash by default, but the on-board bootloader will look for an image on microSD. Without modifying the bootloader, there's no way to prevent it from trying to load off of the microSD. The microSD boot configuration could point back to the on-board eMMC.

Anyway, the answer is to not have a microSD inserted at boot.

3. How can I query my blue on where it has booted from?

I added a note to the above FAQ.

4. Can I tell by the LEDs where the blue is running it's OS?

You cannot tell from the LEDs where the boot source is.

I will do my best to implement these!
