I think Gerald is oneof the more experienced Bretonia players so I would definitly listen to his take on them (but just remember that my Dwarfs took his Bretonians last EuroGT 
But of course it's an honour to lose against such an experienced player as you are. My knights just were too eager to fight that day and you knew perfectly how to use that!
I think Dwarfs and Bretonnians should be friends anyway, fighting their foes together not fighting each other...
Back to topic. Azrael, I think you have a very good approach to the army. A lot good hints have been mentioned already (it seems that austria definitely is bretonnian land as most hints are from here
but in the end it's all a question of personal taste.
I try to always go towards a breakpoint of 4 or 5. Depending upon that I am building knightly brigades of 3 or 4 so that the game never ends when losing one brigade.
At 3000 2 peasants are quite ok (if you want to scratchbuild grails pilgrims you should go for four. As a brigade of 3 peasants + 1 grail pilgrim unit they are most effective).
I always put only one peasant unit into a brigade so that they are not stranded alone too often (and I always smile when an opponent goes on advancing to them because that will be a gain for me mostly). But they are also good as cannon fodder (especially with Aerial Shield as a help).
5 or 6 squires are perfect. Maybe take 5 units of bowmen at 3k. It's a matter of mood what I am taking for my games. Sometimes I take more cavalry commoners sometimes more infantry. When going against undead for example I prefer lots of infantry as numbers are decisive there. Also it helps against Chaos (imo) because you can slow them down perfectly and lose less points on the way. Against Orcs I would take more Squires as it helps against the 4 attacks of the Orcs when you have less front edge.
The only thing I would change is the number of men at arms especially when considering the tactic you are planning (I would take 5 at 3k). If you want to send in your commoners aggressively bowmen are less helpful as normally you will wait to be attacked with them while men at arms can go for it.
I personally dislike the trebuchets as you have to change your whole army fitting to them (and the tactic you should play with that army is not too bretonnian imo). Still they can be interesting to play for a change. But I agree with Schindbua - if you take them take two (because that could be worth all the efforts of designing the army around it).
@wellspring: Have a look at the Trial army list at Lex's Warmuster site. In the section about recommended tournament army lists you'll find the new bretonnian army list with pegasus knights, grail pilgrims and changed trebuchets.
I think Bretonnians are not the Uber-army (at least I think so
) but they are quite stylish and fun to play with especially as with this army you really can send your commoners to the fight without thinking too much about it (with this army I really learned how well simple infantry can do).
But on the other hand you really have to know when to send in your knights. Too early and you lose by breakpoint (see my game against Lex). Too late and you might not have gained enough victory points. Especially the Pegasus Knights are tricky to use if you do not want to give the opponent a breakpoint-present.
Hope that helped,
Gerald
