KiCad help for differential pair routing and silk screen layer
datasheet page 9+10

Comment: the footprint in your picture looks very different from the one recommended by TI. I would either stick with the manufacturers or the IPC ones.

Search turned up: there is a checkbox in layer manager toolbar for the visiblity of references and values.

Comment: KiCAD files can be easily modified via scripts / editors.

MPN is not a standard field which is why it is not shown by default, I guess.
