For Gula's book, once you get to the crow's nest enter the sewer and go where the quest leads you after that.
For Haliwell's pendant, go to the forbidden archives I mentioned in my last post and you'll find a spell to remove the demon's grip barrier. Read the spell outside the door upstairs in the Circle of Trust Inn and you'll find Haliwell.
For the Engineer's sword, go to the Crow's Nest all the way in the back and you'll find a cavern entrance. Take it and it's pretty straightforward from there.
For the Maxos bracelet, look around the walls in the city for little iron rungs surrounded by red light. Pulling those will activate runes on the wall leading to lanilor lane. Once all are lit, talk to the guy in white near the runes. Use the sequence he mentions in the conversation with the dragon-head statue not far away. Straightforward from there.
Finally, for Jake's Ring you simply have to solve the investigation at Madame Eve's which is fairly straightforward.
