After Story Mode

So I finally killed Darth Baras and now it seems I am starting the Revan quest line. I have a quest (that has Play) for a hunt and also Ilum. At what point should I do the Ilum questlines?

Trying to do the chapters/storys inorder atleast on Wwena then the rest are being skipped…

The quests will set you in the correct order. You should be doing Illum after corellia.

Your probably getting the Ilum quests because you are around or at level 50. With how quickly you level up through the early game now adays, that planet was the level 50 area for a while before the expansions came along.
