2 quick questions

[cronj0]

Is there some sort of guide somewhere that will tell you what all the extra items do, and what do myserious scrolls, mysterious books, and valuable elixirs do?

There is no special list. If you play on CCC you can ask other players - most of them will help you ;)
mysterious scrolls: cube 10 of them to get a random rune (no other known function at moment)
mysterious book: part of the new cainquest (act1 quest3)
valuable elexier: increases life and mana for e few minutes, have a high sellvalue at gamble-npc's
