The comics Knights of the Old Republic and Empire (which largely follows Luke's old Tosche Station friends) are excellent too. It's harder to recommend books since so many of them are mired in vast unending series, but I've always liked The Courtship of Princess Leia (Barbara Hambly) and I, Jedi (Michael Stackpole). If you have a lot of time on your hands and enjoy vast multi-author potboilers, I think the New Jedi Order series (20 or more books, I forget) had more than a few great moments.
