I keep hearing "EU names" repeated over and over.

Let's not forget that part of the deal with Disney is that Lucas wrote the story outline for the next three episodes. That would include, I would imagine, naming all of the important characters as well.

That one of the character's names is a recycling from Droids is a telltale sign that this is George that we're dealing with. He collaborated heavily with the original Droids series producers back in the day and as a result a number of things from that series ended up being recycled into the Prequels.

The Boonta Eve race being a big one but there was also:

Among other things.

So they're not "EU names" if they're coming straight from the mouth of the creator.

Whether they're good names or not is an entirely different matter however.
