Either you're playing dumb or you lack critical reading skills. Lets add some context here.
"Go, sell everything you have and give to the poor, and you will have treasure in heaven. Then come, follow me" -- Mark 10:21
Cite the whole story, Mark 10:17 - 10:29. It becomes pretty clear that what you imply with your cherry picked single verse is inaccurate at best. In context, the person being talked to is a well off influential rich kid who sees the following that Jesus has and is trying to jump on the popularity bandwagon. Jesus recognizes this, and rather than say "lol no", he gives him a task that illustrates that the guy wants in for the wrong reasons. The guy was probably expecting to be asked to pay a "donation" or maybe introduce Jesus to some influential people in exchange for some lessons on charismatic speaking. Had Jesus given the guy some other task (e.g. "volunteer 100 hours at the soup kitchen" or "go knock on 100 doors and ask for donations"), the guy probably would have agreed and then sent an intern to do it for him or something and the lesson would have been lost on the crowd.
"If anyone comes to me and does not hate his own father and mother and wife and children and brothers and sisters, yes, and even his own life, he cannot be my disciple." -- Luke 14:26
How about you include the rest of the context? Keeping in mind that in the previous chapter he'd just fed 5000 people:
Large crowds were traveling with Jesus, and turning to them he said: “If anyone comes to me and does not hate father and mother, wife and children, brothers and sisters—yes, even their own life—such a person cannot be my disciple. And whoever does not carry their cross and follow me cannot be my disciple.
It should be pretty clear from that that this is a crowd of people hoping to see more miracles. They want to jump in on the popularity train, be entertained, and get some free food out of it. In this context, it's pretty clear that he's warning these people that life following him isn't going to be an all you can eat buffet of fish, bread, and inspirational speeches. In fact, it's going to really suck to the point that you'd have to hate your family to want to do it (which, if you follow the endings of the rest of the disciples, later turns out to be pretty true).
"Permit no woman to teach or to have authority over a man; she is to keep silent." -- 1 Timothy 2:12
Look at the entire chapter (or even book, 1st timothy is shorter than some slashdot summaries). This is referring to roles within the church, and it assigns some equally important (though less public facing) roles to women.
"Slaves, accept the authority of your masters with all deference, not only those who are kind and gentle, but also those who are harsh." -- 1 Peter 2:18
Good cherry picking and leaving out the passage in front of that:
Therefore submit yourselves to every ordinance of man for the Lord’s sake, whether to the king as supreme, or to governors, as to those who are sent by him for the punishment of evildoers and for the praise of those who do good. For this is the will of God, that by doing good you may put to silence the ignorance of foolish men— as free, yet not using liberty as a cloak for vice, but as bondservants of God. Honor all people. Love the brotherhood. Fear God. Honor the king.
This is clearly talking about not running around telling the civil authority to go fuck themselves because god said so. In fact, I could make the argument that the spirit of this is basically attempting to separate matters of church from matters of government. e.g. if you want to go burn some people because you're pretty sure that they're a witch, but the government says no, you do what the government says.
Another thing you're either intentionally leaving out or otherwise ignorant of is what slavery looked like at that time in history. It was both ubiquitous and also about as far from the image that comes to most peoples minds when you say "slave" as you can get. A much better translation in modern language would be "servant" or "indentured servant".
