Firelands achievments questions.

[Anakso]

So, first off, I wasn't sure if I should post this here or in the achievements forum as it kind of pertains to both, if a mod feels it'd be more appropriate in the achievement forum feel free to move it =)

So, my guild is currently only 6/7 (yes, I know, months behind and all that), we're close to a rag kill but didn't get it this week, with the nerfs incoming and a rag kill pretty much guaranteed next week, nerf or no nerf, we've decided to knock out as many of the achievements we can before we start working on the boss's in heroic. Below I'll just list each boss, and how I believe the achievement is done, and list any questions I have about it, so if anyone has done the achievements before you can give advice or hints etc. in no particular order.

Beth'tilac - Death from Above. http://www.wowhead.com/achievement=5821#comments
Now this achievement seems to be mostly straight forward with 2 details I'm unsure of. basicly we'll just get the drones down to about 10-20% or whatever % we feel is safe to push it too, without accidentally killing it. the main detail that seems sketchy is the first drone. it's states in one of the comments on beth'tilac that the first drones energy will be depleted AFTER the first time beth comes down, now does it work out in a way that, by the time your upstairs team is upstairs again the drone is either still downstairs and about to go up, or still upstairs, making it possible to kill it? I hope so.
The only other thing is the last drone, by the sounds of it you don't kill the last drone at all because it's still up when beth comes down for the last time?

Shannox - Bucket List. http://www.wowhead.com/achievement=5829#comments
Fairly self explanatory achievement here, just drag him from X to X till all criteria is done and then kill him, presumably dps will kill rage well kitting him then lower both rip and shannox , waiting till we've finished kitting to actually kill rip and then shan.

Lord Rhyoloth - Not an Ambi-turner http://www.wowhead.com/achievement=5810
Also a relatively simple achievement, just zerg dps on the right leg, only thing I'm unsure of here is if things like howling blast or holy wrath which will hit both legs, cause this achievement to fail, reading the wow head comment some people say it only fails if the meter actually goes into the left side, so should be fairly simple.

Bael'roc - Share the painhttp://www.wowhead.com/achievement=5830
Another self explanatory one, we'll have 1 tank, 2 heals and 7 dps, one being a shadow priest who can take the full first shard then have 3 groups of 2 rotating, so from there it'll be a fairly easy dps race.

Alysrazor - Do a Barrel Roll! http://www.wowhead.com/achievement=5...-a-barrel-roll
Another simple one, but can't really aim for it, this will just be one we get over time as we tick each one off.

Major'Domo - Only the penitent http://www.wowhead.com/achievement=5...itent#comments
Okay this is the one that confuses me, so as i understand it, it's the trash you do the achievement on and NOT the boss?
If so, you bassicly have people go and click the orbs (3 per orb or something) then you click them and everyone has to avoid the next kneel to the flame by kneeling or sitting, and forms can bug it (unless fixd since the comment i read)
Now, the main thing that I'm confused about here are the actual orbs, where are they? I've only ever done a quick once over with my camera but never actually seen them.

As for ragnaros achievement, we most likely won't be doing this on our first kill but if you have done it then feel free to explain. that's one I haven't looked up yet.
