Here are the two 2 volume commentary sets and the 2 Study Bibles I would recommend.
The Bible Knowledge Commentary - 2 Volumes OT/NT (from two professors at Dallas Theological Seminary, Walvoord & Zuck)
The Believer's Bible Commentary - 2 Volumes OT/NT by MacDonald
*(if you can afford both sets, I'd recommend getting them)
The MacArthur Study Bible
The ESV Study Bible
*(these two Study Bibles are my favorites because of their extensive commentary .. for a study Bible that is .. the ESV Study Bible is only available in the ESV however, MacArthur's is available in several translations // and both are available as part of the
Logos Library System .. as are the 2 volume sets I recommended above)
Also agreeing with Timewerx, BibleHub has some excellent commentaries available for free online. See:
John 1:1 Commentaries: In the beginning was the Word, and the Word was with God, and the Word was God.
