Greetings Warthog.
You said: "Think about it. You Protestants believe that the teachings of the Apostles written down in the books of the Bible are infallible, but you believe that those Apostolic teachings that DIDN'T get written down are not??? The Bible itself tells you directly that both are valid, and in fact the Bible is the "lesser" source compared to Tradition. (can't recall specific chapter and verse at this point, and I'm away from my references, but one source is St. Paul)."
Question: What items, necessary for salvation, that the Apostles have said verbally and have been passed down in Tradition am I missing from reading Holy Scripture? Please let me know. Thank you.
