Order is not important, but the last star cannot be gained if the bar on the interior door leading to the back exit has been broken. You must enter the cave from the rear entrance and make your way to the barred gate (you don't have to unbar it, just walk up to it).

If there are bandits in the Cassardis entrance side of this barred gate (common when both Deep Trouble and Deeper Trouble have been completed), it is likely that they have unbarred the gate, in which case you will need to wait until NG+ when the area will be reset.

The other two locations described are spot on and Knowledge should be triggered without doing anything special besides walking to those areas.
