Can you show clearly in the text where it says Mary was immaculately conceived and believing that is a pre-condition for salvation?

You may want to reference the catholic encyclopedia online before you attempt to answer.

Heck no — and so what?

The Scriptures are not the last word on the authentic faith. As a bible-believer, you ought to believe that, unless you believe only the parts of the bible you like.

It’s not necessary to “know” anything to be saved. People incapable of reason or self-knowledge are saved all the time.
