Did you order the bars through Veloce Velo? If so, I hope they give you a "re-fit" or "mini-fit" after you/they install the new bars. A lot can change when you swap bars. They all differ so much in shape, drop, and reach. How about the position of the shifters? If they are "toed in", "toed out", or straight? How far up or down the rotation of the bars are? You might even have to go with a different length stem. If any of these are "messed up", it will negate the investment you made in your fit.
Nice report. Pro fits are so important to obtain optimal efficiency and mitigate pain.

On the rotation of the cleats. Do your cleats float, or are they fixed?
