Understood on the coat color. There are many greatcoat mods out there, and the ones I have seen do go for the dark navy blue. So, why do another one? I have cjhosen a color that I like the look of, and also, the chaces are the coats got lighter and washed out some when in the field.
Regarding unit names, if removing ui has that effect (I don't know why) just revert to the original file and try replacing the unit cards with ones from the vanilla unit using PFM "replace" function.
