Most of the commands of the OT pertain to trying to teach people how to live. The Law was a deliberately temporary measure to tell people that they should have certain attitudes, and approach life with certain principles. He did that by commanding actions with the idea that they would see the attitudes behind them. People failed at that.
Most of the commands, while about surface behavior, are not really about surface behavior, but about holiness. There are principles couched in what seems "despicable and nonsensical" about God's character, his holiness, and how people could live lives of holiness also. So it's not so much about shellfish and animals with hooves as it is about what all that stuff represents in symbolic ways.
You ask, "Why does God seem so primitive?" One thing you must see is that God spoke into their culture in forms and language that they would understand. It's not "primitive" as much as it is culturally different than our culture. Remember that explosive cultural changes have happened in the past 150 years. You may define their cultures as primitive, but they were sophisticated in many ways, and just different than ours.
Of course God knew objective morality from the start. Objective morality is rooted in his nature. But you'll notice and in the Bible God does not dictate the shape of society. He doesn't seek to form a "perfect" society, because no society is perfect (since it is a society of fallen humans). He rather speaks into the shape of society as it exists in those times and encourages his people to live holy lives in that society. He does not dictate an ideal kind of government (monarchy vs democracy); he doesn't dictate a system of marriage (arranged vs love) or even polygamy vs monogamy; he doesn't dictate the way that a society is stratified (slaves and free); he doesn't dictate a certain sort of economy (market economy vs barter). Every social structure is flawed. Instead, as I said, his goal is to raise up a people holy to himself.
You ask why God is so bloodthirsty. It depends what you mean by that. If you mean the sacrificial system, we can talk about that. If you mean warfare, we can talk about that, but I don't just want to talk until I know what you're referring to.
You accuse God of being egotistical. Do you perceive your parents as being egotistical by requiring that you learn to obey them? I hope not. Obedience to authority is an important part of a working social environment. Are teachers egotistical when they insist that you be quiet in the classroom and listen to them? I say no. Classroom order is essential to the model of education we have chosen. Assuming that God is truly deity and divine, and that he made humans to have fellowship with him and to give them life, it makes sense that other allegiances and false divinities will deprive humans of a legitimate relationship with the authentic deity, and deprive them of life that only he can give. To insist on the truth isn't an expression of egotism, but of genuine compassion.
