The "riches" are puzzles on the walls in the Ice Cave.. You need to have a certain skill level to do each (like Crafting, Woodcutting, or Agility). When you do them, you will be given extra experience in the skill.
If you did the Romeo and Juliet quest its that same house.
Yes, every few months Runescape pumps out a new quest ranging from beginner (very easy) to Special (practically impossible to complete without dying).
The 2008 Christmas event
Rune mechanics
You will have to find out on the day, like everyone else.
its not a certein level that you need you have to complete all the quests if you do do this and a new quest comes out you cant wear it until you do that quest

It is a quest, that introduces a new potion into the game, and is a prerequisite for other quests.
It is in a way for a sort-of new player, but it does get easier, there are guides out there that show you what to expect.
The reason simply is, that Jagex doesent want people to help the people doing the quest, (Sal's Realm, Runescape Wiki, ect.) so they keep changing it. It has been changed 19 times on record.
There is no way to produce new Christmas Crackers, so you can only buy it from another player. That's precisely why they are so expensive.
There is no ruenscape credits because you can not beat the game there is always new skills, quest, levels , etc.
