It is not really necessary to kill Murmur to get the first key frag. He does not aggro until attacked -- though since you are there...
Those classes that have stealth capability can get to the 2nd frag in the Steamvaults easily. My resto druid has lead rogues and druids down there on several occasions. If you are going to do the dungeon anyway, great, if not, then a fifteen minute in and out will do.
As pointed out you will need to have a flying mount (or druid flight form) to get into Arc, but you do not need to kill the first boss to get the key frag. That being said, since you ARE there you might as well... As the mobs are tighter together I do not think stealth is an option, but if you are doing a frag run it shouldn't take a team more than 20-30 min to do and only one person needs to have the key (similar to Strat/SM/Gnomer). Alternatively if your guild has cleared SV/Arc they could sub you in to loot the vase. We have done that a few times with new guildies when the daily was one of those dungeons.
The Black Morass event is loads of fun. I sign up to heal it every time the guild puts it on the calendar unless the person needing it is a healer. For many people it is their first truly long fight, so it is a right-of-passage event. Afterwards the idea of 20+ minute fights no longer seems that out of reach, though of course from BM those fights are still a good ways off. On Heroic mode it is such an adrenaline rush!
Best of luck!
