It's also available in the JW Library app. Both are 100% free, no signups or membership, and makes reading so much easier and more enjoyable.
I personally find myself comparing the KJV with the original Greek as well as the pre-Challoner version of the Douay-Rheims when I want more insight into certain passages.
Commentaries also provide interesting insights. They typically cite the translations that were used as well so you can see how their conclusions were drawn

Another book similar to Riplinger's is "Corruptions in the New King James Bible" by Jack Mundey. The writing style is a little enthusiastic, but the author compares several editions of various bibles, showing where and how they changed over time. Both Mundey and Riplinger draw the conclusion that the NKJV and NIV are deliberately changed to mislead people, and therefore are Satanic, though neither one makes any point about the KJV's edits themselves, such as the name of God or translations of "Hell" as I've mentioned earlier.
It's actually reasonably readable but there are differences in meanings due to the decisions of the translators. This is true with all translations, so not a direct criticism, but the NWT tends to differ on areas where the JW belief system itself differs from the mainstream. So personally I'd suggest avoiding it as it will give the new reader a very exclusive perspective on the faith.
There are lots of answers to this question floating around the thread. Maybe mine will be helpful:
First of all, so much of the Bible references and builds on itself that it's a battle to establish the initial framework of knowledge so you can try to fill everything in.
The most important question of Christianity is, as Jesus put it, "who do you say that I am?" Start working on this with a Gospel (either Mark, more focused on a clear message; of Luke, more of a detailed narrative). (Matthew was written for a Jewish audience, so the perspective isn't as helpful, and John is just different in ways that make it better saved for later.) After this, read Acts, which finishes the story begun by the gospels. If you pick Luke, then you have the advantage that Luke and Acts have the same author.
Read Genesis. There's so much to unpack in this huge book. Jordan Peterson released lectures on many stories of Genesis as early podcasts of his; they do a good job of presenting the stories in the modern day, and are probably his best work, far better than recent work.)
Exodus. It is narrative and explains God's relationship with the Jewish people.
If you want to keep digging into that story, you could go next to Joshua and Judges. But I recommend next reading 1 and 2 Samuel and 1 and 2 Kings. They're the story of David, who is the archetype of a God-fearing, yet only human, Jew.
As to a "proper" way: slowly, carefully, repeatedly, with humility, and with help.
Am I missing the "proper" way of reading it? But if there is, that would eventually just leave to cherry picking...
