The quoted figures for the Superpro arms will vary depending on how much lift you have. Depending on how much stuff you have screwed on the front, KTFR101HHD may well raise the front more than 2"
Also remember that the extra caster achievable with the Superpro arms is provided by moving the top ball joint REARWARD.
Moving the top ball joint rearward DECREASES clearance, although only slightly compared to an equal movement of the bottom ball joint. So if you max caster adjustment within the Superpro arms, that actually reduces clearance slightly. Moving the bottom ball joint FORWARD with the eccentics on the lower control arm will increase caster AND guard clearance, but It it is not always desirable to max out the adjustment of the eccentics to chase greater clearance.
I would expect normal procedure to be to set the adjustable top plates to the same setting on each side and then fine tune with the eccentrics on the lower control arm. Depending on how straight the vehicle is, it may be necessary to set each top plate at a different angle to get a good result.
.25/.5 degrees of neg camber would not concern me at all. Probably steer better and unlikely to adversely affect tyre wear. A whisker more on the left than the right is also good. If anything, the settings you now have may well reduce shoulder wear, particularly on the LSF
A bit more caster on the left is usual and is also a good thing, provided you don't have too much more on the left. If the vehicle tracks nice and straight and doesn't pull to the left on our usually cambered roads, it will be near enough.
The numbers and plate settings look like there is a good chance that your installer has tried to give you what you asked for
