Hey NVL, the first two posts in Palmtree's link contain the WT Literature cites for the 587/607 king list issue.
In general, this site is a treasure trove of WT quotes: http://www.qwotes.info
Here are some quotes that tell Witnesses not to study the Bible on their own or have their own ideas about the Bible:
*** Watchtower 1967 June 1 p.338 Move Ahead with Jehovah's Organization ***
12 How will we put these four things into effect? First, study: We may think of study as hard work, as involving heavy research. But in Jehovah's organization it is not necessary to spend a lot of time and energy in research, for there are brothers in the organization who are assigned to do that very thing, to help you who do not have so much time for this, these preparing the good material in The Watchtower and other publications of the Society. But you do not study enough? Take this suggestion: Often the very best and most beneficial studying you do is that done when you read a new Watchtower or Awake! or a new book with the joy of getting the new truths and a fresh view.
*** Watchtower August 1, 2001 p. 14, par. 8 ***
First, since "oneness" is to be observed, a mature Christian must be in unity and full harmony with fellow believers as far as faith and knowledge are concerned. He does not advocate or insist on personal opinions or harbor private ideas when it comes to Bible understanding. Rather, he hascomplete confidence in the truth as it is revealed by Jehovah God through his Son, Jesus Christ, and"the faithful and discreet slave." By regularly taking in the spiritual food provided "at the proper time" — through Christian publications, meetings, assemblies, and conventions — we can be sure that we maintain "oneness" with fellow Christians in faith and knowledge. — Matthew 24:45.
