The bone spears and BF map problems are well known issues.
Someone else had a problem with that speech clip being played in the wrong spot. It was before getting to the cell in the arena hallway where it is suppose to be played. This was in the demo or maybe shortly after release. I don't recall having any out of place speeches in the demo or with the released/patched version.
The reference to the white rum was for the quest to steal a book from General Bram's room, gotten from the merchant Tully in the citadel.
The number of dialog lines were either cut or restricted from the start due to localization costs. They may have been planning multiple speeches at the end of the act, that may have originally been intended to be a required quest, or there was a miscommunication somewhere about what needed to be added to the story or cut from the dialogs.
There is a similar problem in act 2 when talking to the alchemist. After agreeing to get some items for him, the dialog advances prematurely. If you talk to him again right away, you get the speech that should only come after bringing all the items (that doesn't cause any problems, though, just confusion).
The Larians are working on another patch.
