Normally a normalisation convention is adapted so that |a|^2+|b|^2=1. The actual intricacies of quantum computation are incredibly complicated (and beyond my brain at the moment - I'm an undergraduate) but I heartily recommend some of DiVincenzo's more readable papers, like that earlier (it's quite understandable and doesn't really require much background knowledge) and the slightly more practical http://arxiv.org/abs/cond-mat/9911245. If you don't know what kets are, the wiki article on Dirac's bra-ket notation is somewhat useless; I suggest Dirac's "Principles of quantum mechanics" which will explain the whole lot from the very beginning.

And yes, I did register just to post this...

That reminds me of an awesome t-shirt I saw somewhere with the following written on the front:

You keep your "10 types of people" shirts, I'll stick with shirts only 1/10 of the "10 types of people" wearers will understand.
