Question
Why the greatest knowledge stores in some book (Bible)?

Answer
This seems to be a reference to the value of the information (namely about God) which the Bible contains, not that the Bible somehow might contain all knowlege about all things or be great in any sense other than its value to those of us who thereby find the path to Heaven.  It is more Protestants than Catholics who talk like that since they have nothing to go on but the Bible itself (never mind how heavily dependant they nevertheless still are on their various contemporary "interpreters" to "understand" it).
The reason Catholics are less inclined to speak thus of the Bible is that God's revelation really comes through Jesus Christ himself personally while in this earth those millennia ago, and then through His Mystical Body the Church ever since then.  The Bible itself comes from the Church, as does the whole of Christian teaching, some of which recieves scant mention in the Bible itself (including such fundamentally basic teachings as the Holy Trinity)
So if anything, such a way of speaking of the Bible must at least run some risk of Bibliolotry, and that is also another reason to see it so seldom among Catholics.  The central role of the Bible in all Divine Revelation remains however certain and total and irrevokable.
Hope this helps, and sorry I could not help with the other question (about degrees of Celestial glory).
