I would question the itnterpretation of "knowledge of good and evil". My Bible (New Jerusalem Bible Standard Edition) has this in the footnotes:

"This knowledge is privilege which God reserves to himself ... it does not mean Omniscience which fallen creatures do not possess. Neither is it moral discrimination, for unfallen man already had it and God could not refuse it to a rational being. It is the power of deciding for himself what is good and evil and of acting accordingly, a claim to complete moral independence by which man refuses to recognise his status as a created being. The first sin was an attack on God's sovereignty, a sin of pride. This rebellion is described in concrete terms as the transgression of an express command of God for which the text uses an image of forbidden fruit."

Of course, the New Jerusalem and Tyndale House represent very different Christian traditions, so it is not surprising that their footnotes differ.
