Here’s a list of all the EU/Legends books in timeline order (with that particular link going to the Rebellion era section). You can filter out different types of books (junior novels, etc.) at the top.
Unfortunately, that doesn’t really address your question of good books set in that era. I haven’t read most of these (only Shadows of the Empire and The Truce at Bakura, only the first of which I recall being particularly good), so I can’t really vouch for their quality.
Wookieepedia to the rescue!
