I think breaking a truce only costs one hell of a lot of stability; not any BB points as such (though any territory conquered will have the normal BB penalty of an aggressor).
EDIT: Damn one minute late.
More for the beginnner: Heh, playing and winning as Byzantium in the first game ever is quite impressive, regardless of the difficulty level. Good luck with Muscowy/Russia, it is a really fun country as well when it comes to warfare (though nothing beats multiplayer in that respect).
