Vanguard Monks

Just wondering what types of weapons monks can expect right now for Level 30+.  I'm at 31 right now and was lucky enough to get Zank (46dps - took me two days to skill up so I could use it).  I imagine that will last me into my mid-thirties or so, but what can I look forward to after that?  What are some of the high 30s and 40s weapons monks should keep an eye out for?  Which weapon skills are we most likely to find good weapons for at the higher levels?

There is a lvl 38 weapon called dwarven martial staff or something like that from a nasty line of quests from Dargun's Tomb.

It has like a 69 DPS rating and letters are in orange (legendary?  heroic?)  Best monk weapon i've seen.

also there is a weapon quest line in Wardship when you have like 12k true faction (not dynamic, use /showfaction) that gives you an item that lets you summon 50 1250dam shurikens every 10 minutes.  Orb of the heavens or something like that.  need a 320 throwing skill to use.

*edit* - i think its a martial staff btw, so get 2hb up.

Do monks at a higher level get a sword like the one the Grandmaster, Britrix Lightstorm,  carries?  Looks like a katana.

There is a legendary martial sword lvl37ish from the Zaraj Arena ... Tranquility i think it was called... it requires 1000 zaraj coins to get though.  Its DPS is slightly better than Zank while giving 21% parry bonus.  Not sure what its graphic looks like.

Is that the big arena thing near Khal?  What do you do in there and how do you get coins?
