A few questions

Just to start out with, here are a few of my pressing questions for you (the rest of the blog will be about this too, but why not have a unique post about it?):

• Why is the Quran organized by sura length and not in chronological order? It seems to me that it would be much easier to understand if what was revealed first was written down first. After all, is Allah a god of order, or not?
• Since the Quran says, "O ye who believe! Ask not questions about things which if made plain to you, may cause you trouble. But if ye ask about things when the Quran is being revealed, they will be made plain to you, God will forgive those: for God is oft-forgiving, most Merciful.. Some people before you did ask such questions, and on that account lost their faith." (Sura 5:101-102), should I even be asking questions about Islam? If truth really does stand out clear from error, shouldn't questions strengthen one's faith? (I am not saying I am a Muslim. I am just asking the question.)
• Since the New Testament (by this I mean the four accounts of the life of Jesus Christ, the books on the early history of the Church, and the canonical epistles) came after the Old Testament (the Torah and the Prophets), we ought to judge it by what came before. In this way, Christians find out whether their God is being consistent and faithful or not. By similar logic (time alone), we should judge the Quran, revealed after the Old and New Testaments, by what came before. Indeed, the Quran itself exhorts us to do so. Indeed, even in fields like biology and geology, the past ought to be the key to the present. So, my question is, why is one supposed to judge the Bible by the Quran?
