Hall of Monument quests

I've got a few questions regarding the Hall of Monuments:

First off, I got a tapestry thing and chose to put my armor on display. Well, I'm a ranger with 15k druid armor, which I got from Marhan's Grotto. It gave me the option to display Marhan's Grotto armor. Well, instead of my 15k druid armor, it showed the mesmer's 15k enchanter armor, which I don't even own. Does this just show that I have armor from Marhan's Grotto? And I also have 15k gladiator armor on my warrior. Does she have to come into the Hall of Monuments as well, for her armor?

That brings me to my next question - The armor that's on display, will our Guild Wars 2 characters be able to wear it? I heard they can take out weaponds and use them and such, but...yeah.

Also, speaking of weapons, according to guildwiki, the tapesty for that is apparently for unlocked high-end weapons obtained from Eye of the North. Does that mean my greens from other campaigns (which I use them and not golds) will be unavailable to use in Guild Wars 2?

Now for the title tapestry - the only titles available to display are PVP only titles. What about survivor, wisdom, protector, etc.? Where are those and why can't we see them to display? And again, for each character's title, does that particular character have to come to the Hall of Monuments to display it, or is it based account-wide?

Hero tapestry - My fiance said that apparently the only heroes you can put on display are ones that have had armor upgrades, like Stolen Sunspear Armor, Ancient Armor, etc. I don't think that's fair, not everyone can farm/afford those armor pieces. And runes don't count, or so I heard.

No questions about the mini-pet one, at least not yet. hehe

So any information on these questions will be greatly appreciated. Or, are certain things not showing yet because it's just preview weekend? Also, do you have to beat Eye of the North to be able to play Guild Wars 2? I've heard the stories both ways. Thanks!!!
