The Bible contains 150 psalms. The Septuagint numbers them slightly differently from the Hebrew Bible, the Septuagint (Greek Old Testament that Jesus used) has 9th and 10th psalm of the Hebrew Bible as the 9th psalm so they are all off by one up until psalm 146 and 147 which are 147.1-11 and 147.2-20 in the Hebrew so they both end up with 150.
In the King James version the last Psalm is numbered 150
Approximately in the center. Stand the Bible on it's binding, open the book right down the middle, and you should find Psalms. Proverbs is right after Psalms.
Depending upon the Bible used, Psalms is the middle book with Psalm 117 as the middle chapter (KJV).
There is some speculations, but it is widely believed that David wrote the book of Psalms.
