Be careful that you don't slip into the Qur'an-only heresy. Allah (swt) did not just throw the book down and say "Memorize this, you'll have a test on it all next Friday." No, He revealed it over a 23 year period to the Prophet Muhammad (saws) who was our teacher. This teacher taught us how to best apply this book, and we find his lessons in the hadith. The female sahaba covered their hair because that is what the Prophet (saws) taught them.
The path of Allah (swt) has been well trodden by millions over the last 14 centuries. Why not walk that path first before you go off to places that are less well known?
you're right, I have been focusing on the Qur'an maybe a little too much... it's just that I read a few things claiming that there are some hadith that are not to be trusted, the chains of transmission too weak. I figured the Qur'an is protected by Allah and will never be distorted... so I've been relying on that. but of course there are some truths in the hadith...I will have to look into it more...
