It never occurred to me before to have a "personal canon", but I guess now you have to if you want to stay interested at all, since no one can be into everything. So: the original version trilogy, the Daley Han Solo, any Marvels that weren't directly contradicted by EMPIRE/JEDI, the Zahn trilogy and DARK EMPIRE. Pretty much anything that pre-dates the sweatshop factory mentality. (I guess the prequels too, what the hell. Only because, since at least 1979 they were on the horizon somewhere and don't exist purely because of board meetings. Sort of.)
