Well, ideally, a balance of jedi to padawans (I would assume that some padawans would run away to the action) and I think that there'd be a lot of Jedi sentinel and consular types because the Order is still psychologically reeling from the war with Exar Kun. So in a sense, they are cautious about getting into another war and being tempted by the Dark Side, which is why the masters are sitting on their hands. The Jedi have been deliberately not prepared for war on this scale.
