Martial stats (hit/damage) should draw from typical attacks. Creatures with spell like abilities (including breath weapons) should find an equivolent spell level to their most powerful ability and enter that spell level under Max Spell Level. A dragon's breath weapon would count as a strong special attack as well as a spell level appropriate for its damage output.
