Yeah I just do my class quests in pace with the world quests. You've probably noticed that class quests "coincidentally" go through most of/all the major questing hubs on a planet, getting you to do all the other quests by taking you near where you can get others. (It kinda ruins the story immersion for me slightly, knowing my story is dictated by excuses to go to each of these hubs, but it's okay.) So you should probably be doing all the quests in each hub too, unless you're pretty overleveled(and don't feel the obsessive need to do everything on a planet before you leave).
