Is the God of the NT the same angry God of the OT? I have heard things that make me scared to death to read the OT. (no kidding) Yet all of the Bible should be read I would assume.
Welcome to CF! I have read the whole thread, and those engaging you here make me proud to call myself a Christian! I sense much love towards you, and also a sincerity within you.
Let me point out that G-d is not some old bearded guy in the sky waiting to strike you dead at your first mistake. He doesn't even want to make sure you never have any fun!
He actually LOVES you, enjoys your company, and has made room for your personality in His Kingdom. When believers say something you can't quite accept, this is a prompting for you to seek understanding.
I do AGREE with you, that the OT is NOT the place to start reading the Bible. Start in the Gospel of John. Read straight through the end of the Bible like a book. You'll get to all the important stuff first, and the really important stuff repeatedly. I would go so far as to say don't even be distracted by questions. Just READ IT. Soak it up like a sponge, just to see what it says.
This requires humility, because there will be things you know you don't know what it means, other things you think you know what it means, and other things you think you'll KNOW what they mean. And all of that will change quickly
Some things may become really nagging questions, and the best answers anyone could give you would be what Scripture to read that develops the idea, so you can come to your own understanding, coupled with knowing G-d personally. (Rather than being content with just duplicating what someone else says)
When you exert this type of effort, you will develop a base of understanding that will enable you to discern the intent in the OT. I will tell you to collect bookmarkers, and when you get tired of your current reading, start in Genesis and put a bookmarker to record your progress, use one in Psalms, and since Proverbs has 31 chapters read, 1 / day. Today is the 10th

Something in that chapter will apply TODAY.
Do you have a hard-copy of the Bible? If so, what version(s)?
