Your gallery photos look good! Exposure looks fine to me, too.
X-rite makes several products. The ColorMunki is one of their calibration products. I have an older Eye-1 Display 2 device.
I can see all the tuning knobs (sorry if that's the wrong terminology). They don't contrast with the background a lot, but I can definitely see all the parts.
You need to make sure that the flashes have enough power when used with the umbrellas at the distance and aperture you are shooting at. One of the photos was shot at f/5 which I would think would be wide enough, but I don't know the rest of the details, i.e. distance.
If you want less detail in the back drop you could increase the distance between it and the guitar. You can use a fairly wide aperture and keep the face of the guitar in focus when shooting the guitar straight on. The back drop would then be softer as the DOF wouldn't include it.
