Whofan is definitely on to something there. In addition to the comics WF named I recommend Knights of the Old Republic, the adventures inspired by the video game featuring Zayne Carrick and Gryph. This series recently concluded its 50 issue run.
There's currently Star Wars: The OLd Republic comic being published right now, in separate miniseries, that isn't quite as good. Knights are all collected in trade paper backs now.
Crimson Empire 1 (Part 2 isn't as good, though it does introduce a major character in the NJO series)
Dark Times: I really enjoyed the first volume.
