You have options of many different versions: KJV and others. We are currently using the NKJV (New King James Version). It uses less old English words (like thee and thou). Make sure you use a translation, preferably by a group of people, not a single person. A group keeps individual biases to a minimum.
Commentaries are not needed. God says what he means and knows how to say it. You can understand the Bible for yourself. Sometimes (and not often) it takes a while to catch the meaning. Sometimes after many readings. Sometimes another person’s opinion helps (but remember it is only that person’s opinion). Avoid someone who just paraphrases what he thinks the KJV says; it needs to be a translation from the original Hebrew, Greek and Aramaic.
My wife and I have been reading together for 47 years. You must start somewhere. You really can’t get past “Day One” (just starting to read - or - listen). As far as the actual place to start, I started at the gospel of John. As a new Christian the Old Testament was difficult for me. Yet you need the Old Testament to understand the sacrifices, religious seasons and history. A regular reading place (like a room, or the kitchen table) and a regular time are really helpful. We read for 47 years that way.
You will never reach day 17000 without starting at day 1.
