consider reading jeremiah before lamentations, it's not entirely necessary but it may be helpful to consider. if you get confused while reading nehemiah cross-reference it with ezra which discusses the same events differently
also you should definitely read the epistles to the romans and to the hebrews after revelation but before you go back and read leviticus and deuteronomy for added clarity regarding the law in light of christ's death. note that my three favorite old testament books, proverbs, ecclesiastes, and job aren't even in this list because they aren't necessary to understand the biblical narrative but if you're convicted by the gospel you'll probably just read every other book in the bible that isn't in this list anyways
also make sure to watch ika musume in full twice, print out flash's reimu pic a bunch, and tape her all over your room after reading the acts but before reading revelation to get the full shinryakulyptic experience. consider reading it with koishi as well
