I'll post my personal ideas, and yes, more bashing of Harke's ideas.
(j/k)
First, I do not few the Lhutonics as sneaky. Why must the diplomats always have a sneaky under-current? I view them as noble enough. They know of the Imperial strategy but avoid using it with Redguards, as they know that Redguards fight best individually. However, they do believe that strength comes in numbers, so they might have quests like "Go with this group of four knights and kill the evil witch." etc. They use the best items they can get their hands on and are basically a hybrid of Imperial and Redguard style. They are diplomats, but if that fails they can be fierce, well armed warriors. They do not, however, accept any but the least offensive, to them, magic.
Next, the Forebears. Hardly lazy, these are very well trained in Imperial styles and are armed with Imperial weapons. As I said they are not lazy, instead they feel like crushing in the crowns and despite the commander's best efforts, the knights often break ranks if fighting enemies like the crown. They allow magic use, but they too have their limits. No conjuration, necromancy, illusion, some more of the 'worst' spells and they consider it dishonourable to down an enemy with magic like both of the other houses. They sometimes have a small group of spell casters in battles, but this is only in case of extreem need. Though they are Imperialized, they are still Redguard at heart. They often use mercinaries and sometimes diplomacy, but in the latter they are very stubborn, especially with rival knight orders.
Finally, the Crowns. They avoid magic at all costs, though they do allow potions and, perhaps, enchanting. They are very individualistic and their 'evil witch' quest version would be more like: "Go alone into the witch's lair and kill her." In other words, they believe in the individual honour of a hero to the extant that, of the three knight orders, they are considered the 'Hero makers'. They only use large numbers incase of a large-scale attack, such as on a Forebear fort or a dragon. (By the way, I should note that all of these mentions are just examples, I'd hardly expect a large scale knight vs. knight attack and I don't think having a dragon would be a good idea at all, though witches seem reasonable enough). They are warriors, not diplomats, proud, do not like to hire, and well trained in Yoku styles.
So in my view, the knight orders, though affected by political views, rather represent the Redguard, not the faction. I think that's all I have to say, other than I think that most magical services should be provided by a priest, that there should be a temple per order, just a small one, and that, in some cases, magic use will have to be sanctioned by priests or a ranking knight first.
