Done with Smuggler's Run. Probably my favorite of the three, exactly what it says on the tin ("A Han Solo & Chewbacca Adventure"). That Ematt guy from the Leia book played a major role in this one too, so I'm thinking he's definitely in TFA. Perhaps the middle-aged military type from the casting notice way back when? He's 20ish around the Battle of Yavin, which would put him in his mid-50s in TFA.
Lost Stars is a lot longer than I realized, so I'm going to take a break from this stuff and read something else.
