Balewood is the easiest place to miss quests, and as you have noted, the wiki page has not been completed yet. I made a run through Wildermore a few weeks ago and wrote a rough guide to help people find missing quests, though.
*digs out guide* I made this guide in direct response to someone else's comments, but you can still use it to hopefully guide you along. The coordinates of each ent inside Balewood are noted, as well as a few of the quests along the way. See if the below helps you. If you still can't seem to find the missing quests, let me know and I'll see if I can find the exact quest progression.
