Good to see you back. I'm not sure I understand your question, but reread Jannah's post. It seems pretty clear that people make their own choices (sometimes in spite of religious teachings). Also, one's level of personal faith is only known (or most intimately known) by God (ie, who are we to judge others).
To put it simply, in terms of traditional Islamic teachings, the Qur'aan is revealed to teach us about reality, while the authentic sunnah (traditions of the Prophet) is a means to see how Prophet Muhammad (s) lived those teachings.
To reject all hadiths based on the fact that some are fabricated is kind of like saying, l'm going to reject all books of knowledge because some are actually just fictitious and/or not completely correct and/or made up.
