1.  Regarding the Bryges, their identity is ambiguous.  Like I've already shown you, a number of scholars consider them Thracians.  So the situation is not black/white, nor are Tharcian and Phrygian mutually exclusive.  2.  "Byllones the city" is in fact called Byllis.  The Bylliones are the tribe.  Do not confuse the two.  According to this  source "Hammond asserts Byllis was a Greek colony...."  As far was Wilkes is concerned, you should look on page 130 Perhaps the most remarkable development took place at Byllis of the Bylliones, where the original settlement of Klos...was replaced...by a new settlement on the adjoining hill that developed the imposing character of a Hellenistic city.  Regarding the Bylliones, this  source lists them as Greek or at least Hellenized.  3.  That seems like criticism for the sake of criticism.  The fact that regions outside Epirus are shown does not negate the value of the map, or distract the reader.  4.  You are correct that the map needs to be dated.  5.  I'm looking into it.
