Which of the two M.2 slots should I use for my SSD?

If an intel ssd use slot 2 first otherwise use slot 1 first but both will work Not slot 1 does turn off the top 2 sata ports did not test which are turned off with slot 2 Both ports have same speed and abilities but their is a feture difference between the two as the motherboard shows on each port

Does anyone know if this MOBO supports booting from an M2 NVME SSD?

Yes, It does. That I've used this board in that configuration at least 2-3 times. Worked great.

Does this motherboard have wireless LAN and Bluetooth?

No it does not, but it does have a variety of graphics, and supports three monitors simultaneously, four usb 3.0 ports, and 6 sata 6GB ports. It even has headers for an LTP port and COM ports.

The second image points to the 4 blue ports and says USB 3.0, but under the specifications it says "4 x USB 3.1 Gen 1 (blue)". Can someone confirm if they are 3.0 or 3.1?

It's only 3.0. Newegg is wrong.

Unlike other Asus motherboard I have used in the past. There is no BIOS provided by Asus on their support site for this ASUS PRIME B250M-C/CSM motherboard. Can I use the BIOS from the ASUS PRIME B250M-C motherboard? If so, where can I get the BIOS flashing tool for my ASUS PRIME B250M-C/CSM?

The Prime B250M-C/CSM and the B250M-C are one in the same. The BIOS flash tool comes on a disc included in the box.

Where can I download remote management tools, not on disc or website?

that is a intel tool and must be downloaded from them there is also some 3rd party tools for example realvnc has a feature for them too.

This MB support RAID(1) via iRST (on SATA ports)? Thanks!

This motherboard supports IRST with the PCIe M.2 storage.
