My connection's been unreliable lately, so this has been pieced together over multiple sittings:

Someone also brought up the idea that the reason the Chantry was so reluctant to let Alistair go was because he was the son of a king, and that gave them power -- I think that's right on target and answers a question I'd had for a long time about why the Grand Cleric was so mad. Thanks! 
That's one possibility, but I don't think it was
that common knowledge that Alistair was an heir to the throne.
From my understanding of Alistair's recruitment, the Grand Cleric was practically waving full Templars under Duncan's nose. I suspect that her motivations was that she wanted to infiltrate the Grey Wardens by getting a full (which is to say, lyrium-addicted and thus more controllable) Templar into their ranks. Picking up Alistair, however - someone who had most of the training of a Templar without the lyrium addiction and whose loyalties were already suspect - meant that the Wardens came out ahead instead: Instead of recruiting a full Templar that could be influenced by the Chantry and become a mole in the Warden ranks, they instead get a trained Templar who puts loyalty to the Wardens well over loyalty to the Chantry and who may well be willing to let Templar secrets slip to the Wardens.
It's also possible that the Grand Cleric wasn't actually up to anything underhanded, but just wanted to make sure that the Templar recruited into the Wardens would be one that would uphold the reputation of the Templars, and...well, we know what Alistair's like. Either way, though, Alistair certainly represented the risk of Templar techniques spreading outside the Chantry in a way that most Templars probably wouldn't.

I don't think the exchange between Duncan and Cailan was a false one. They each seem to trust the other, at least to be who they are.
A common piece of advice for people assuming a role is to
never drop the facade, even when you think nobody is looking. Partially because someone
might be looking, and partially because it's easier to stay "in-character" when you remain in character even when you don't have to.

The thing that still baffles me about Ostagar is what David Gaider said about Loghain. He said that, up until the last minute on the battlefield, Loghain wasn't so sure that he was going to withdraw his troops. But since - even before Ostagar - he and Howe were already planning something (murdering the Couslands, making contacts with Uldred and his lackeys, poisoning Arl Eamon), if Loghain didn't withdraw, how were Howe and he going to proceed with their plan?
Loghain didn’t know about the Cousland thing until after it had happened.
Regarding the rest… Loghain’s other plans weren’t actually contingent on Cailen dying – his
ideal end result was a Cailen who was severed from all “bad influences” so that Loghain could bring him around to his point of view.
As for not being sure he was going to withdraw his troops – well, abandoning your king, your son-in-law, and the son of your friend isn’t something you do lightly. It doesn’t surprise me that, however good his reasons were, Loghain would have been having second thoughts right up until the moment of decision came…

Very true. Duncan was entirely free to reject the strategy if he wished. He tells Cailan that the plan will work, so he believes in it. I think he didn't keep wardens in reserve because they hoped to stop the darkspawn at Ostager, and because all the troops were needed to make victory possible. Also because the wardens had to die leaving only Alistair and the PC to defeat the blight. 
Another possibility is that he felt that if the Ferelden wardens did get wiped out, the Orlesian wardens would pick up the slack.
Furthermore, Duncan’s main priority – apart from slaying the Archdemon if it showed up – seems like it might have been “keep Cailen alive”. With Cailen dead…well, it doesn’t matter if there are ten Grey Wardens or two left in Ferelden if Loghain imprisons them or kicks them out. Thus, Duncan’s strategy may have been to keep all the Grey Wardens close enough to Cailen so as to maximise the chance of having one close enough to help if Cailen got into trouble – or even to form a sacrificial rearguard if Cailen needed to be extracted.

@draxynnus, IIRC, all the mages sent to the king were either Senior Enchanters or senior Enchanters. Or in other words, they should have been some of the Circle's most experienced - and hence powerful - members. But the way the game levels others based on your level, it really makes it difficult to say what their power is really like. The only mages we see a lot of in the novels all seem quite powerful, but I'd be reluctant to try to guess their level.
On the other hand…the level scaling does have minimums. There are areas you’re not supposed to go until you’ve reached a certain minimum level.
That being the case, I’d
expect that if the mages we meet – both hostile (including abominated Uldred) and friendly – were too low in level for the lore, BioWare would have made the tower a higher-level area. Since you can get in there almost right after Ostagar if you want to and it doesn’t hit a barrier scaling down, I think it’s
reasonable to presume that a 5-10 level range would be a reasonable average for the mages at Ostagar. Now, these mages could certainly still be powerful, and they can certainly hit the top-level spells, but they are still likely to be lacking in breadth – if a given mage has specialised in more subtle effects from the Primal, Creation or Entropy schools, it’s possible they could in fact be making a strong contribution without doing anything as overt as tossing a fireball.

I can't really believe that two such highly-placed nobles would independently decide on treachery of this magnitude, nor that Howe would so quickly be at Loghain's side after taking over Highever, unless they were in cahoots to begin with.
It’s possible that Howe knew what Loghain was planning, and planned accordingly.
As mentioned earlier in this thread – Loghain wanted Cailen isolated from his allies, and the Couslands may have been counted among these allies. Before Ostagar, however, Loghain seemed to be holding back from doing anything that can’t be undone – the poisoning of Arl Eamon, for instance, was intended to put him in a coma rather than kill him. As RangerSG says, it’s possible, even likely, that Loghain and Howe conspired to
delay the Couslands, but Howe decided on his own bat to take it much further than Loghain had intended. It may even be that Loghain was a little careless with his wording (saying to “take them out of the picture” or something similar) and Howe interpreted it the way he wanted to.
