how can a so-called perfect being create an imperfect book, and an imperfect world?

The obvious answer is that 

on the scale of God, it cannot happen. 

A perfect being can, and will, create perfection "at will". 

“God can't create a billiard ball 

that is neither moving, nor at rest. 

Rather, he has to settle all of those things.” ** 

And clearly, He does. 

As vast, and at times unexplainable as they can be, 

God’s exquisite abilities contain both modesty, and grace. 

The flawlessness of God's ability to solve 

every variance and characteristic of creation, 

in the moment of Creation, is indicative of a degree 

of perfection that religious believers will never comprehend. 

God does not take place in books, 

and has never informed us that he wishes 

to be venerated, worshipped, or combined with a savior. 

And, you’re right … those who believe otherwise 

are a damned people of their own making. 

I'm not sure what you are talking about. Why would people who worship him be condemned to hell?

He didn't make an imperfect book. There are things that people claim are 'plot holes' in the bible, but they often are just confusing and hard to understand, so people write it off as a lie. For example, the "eye of the needle" in the verse about that rich people and heaven-

Matthew 19:24"Again I tell you, it is easier for a camel to go through the eye of a needle than for someone who is rich to enter the kingdom of God.”

-does not mean the eye of a needle as in a sewing needle. In those days, there was a passage that was tight and called the 'eye of the needle' and you would bring your camel through it, but it was hard. The camel had to bow to go through, basically. So, the verse is not saying that it's impossible for rich people going to heaven, therefore contradicting the verse that says anyone who believes will be saved, but rather it simply isn't something most people understand.
