So, I finally decided to take my first tactical carbine course and the vz-58 was put through its paces.
If you are curious what kind of paces, this was the course:
http://www.ar15.com/forums/t_8_35/494743_Fightin__Carbine_2__Saturday_October_6.html&page=1Several things about my gear and stuff that I learned:
The VZ was definitely in top form, having had a 100 rds (several weeks ago) since cleaning and then going through the drills I encountered zero malfunctions. Ran like a sewing machine(as did the aks, and acr). I cannot say the same for all the ar's, though I imagine that was in part due to some cheap ammo+hot gun and a couple guys with suppressors had some malfunctions toward the end, but good lord the crap on those bolt carriers.
My Bonesteel Hand guards did not heat up very much, even during heavy firing drills. They definitely blow the gas out into the air. I did have a somewhat distinctive pattern of soot on my support hand by the end of the day. I did notice this omni-directional gas evacuation did seem to leave a film on the optic that I could see when administratively handling the gun, but did not in any way notice during firing.
Now, I preordered the hand guards and even though I have in hand a replacement upper (the first batch were cut out of spec and replaced in 1-2wks IIRC) I have not taken the original on off my rifle. This is more due to not wanting to have to try to get it off since I over tightened the set screws, but also in part because I want to see when it will start showing signs of failure. Call it an engineering experiment. In any case, it hasn't shown any problems yet, around 600rds through it, and the optic returned to zero when confirmed in class(I pretty much forced it off and on before class to make sure it would come off if it failed).
The Primary Arms micro dot is still going strong one year general shooting and a carbine class later.
The folding stock, in a "surplus" finish state, reacts negatively to sweat within 2 days. Clearly pretty ferrous. Gray paint is in its future.
The muzzle brake definitely helps tame the muzzle flip. Looking at videos of the class I seem to be producing less smoke than the AR bunch. Just an observation.
Lastly, I found that either a high collared shirt and/or cotton shemagh is in my future to both protect my neck from sunburns during these things and to prevent more 2nd degree burns from brass getting stuck at my neck because of my tshirt/body armor combo. Happened in an early day drill too.
So all in all a great experience. If you have never taken a "tactical" carbine, pistol, etc class I advise you to give it a shot. You will most likely find it both enjoyable and informative. I will definitely do it again when time and money permit.

(I know I should have taken the CZ75b and go all Czech but the PX4 needed a workout)
