Those are good and relevant questions. Let me address them in turn.

Human information is still useful, when not contradicted by information from God's creation. The Bible, Church tradition, and other sources supply information on salvation. My personal salvation views are too complex to fully describe here (and off topic anyway), but I will agree that Jesus is the path to salvation.
As I said, my faith is that God doesn't lie (or contradict himself). While it is true that there is plenty in the natural world we don't understand, there is also plenty that is well established. I don't try to "check the Bible against nature", as if the two were in conflict - but rather use each to help understand the other, helping to make a coherent whole. Both are God's word, and anyone who sees them in conflict is claiming that God is contradicting himself. That's not what I'd expect from a loving parent.
I don't 100% believe every word of the Bible is to be taken literally. That certainly allows me to believe in the Christian God, along with the majority of Christians. It is only a minority of Christians who think every word of the Bible has to be taken literally, as I think you already know.
I think that a faith that sees God as living, dynamic, and still speaking is much better than a dogmatic faith based on a literal reading of only one of many Bibles. After all, which Bible would such a literalist depend on, and why? The different Bibles contain different books, different verses, and different doctrines. All are well known to contain errors and changes. To cling to one - arbitrarily chosen - as being the perfect word of God is simply delusional.
Worse, it locks one into seeing God a petty, limited, impotent, and mean. What other kind of God would be so impotent as to only reveal though one flawed book, or so mean as to limit the majority of the world from seeing his revelation? To that kind of faith - limited to pretending that his or her chosen book - be it the KJV, the Qu'ran, or the Pearl - is the only source of revelation, I would say what you said, that "You would be better off if you wrote one for yourself."
