it is a DOL-001 GC
To my understanding, IPL v1.0 (NTSC-U) is incompatible with Wiikey Fusion, however I have also heard that with Swiss Autoboot flashed it will work fine. Has this been tested? If not, I will be the tester

What do I need to specify, on this order?

Thank you!
Edit:
Also, if I mess up I want to know what is the preferred DOL-CPU to get next time?
Out of these:
[best for beginner, power saving, etc]
DOL-CPU-10
DOL-CPU-11[IPL 1.0]
DOL-CPU-11[IPL 1.1]
DOL-CPU-20
DOL-CPU-30
DOL-CPU-50
