Hmm.. I suppose that "Death before dishonor" would be "shi sen fumeiyo"... although I'm not positive (I don't exactly use the words "death" or "dishonor" very often. ) I know that "fight to the death" is "shinu made tatakau".
To pronounce Japanese words is easy. Every vowel gets pronounced (for example, 'made' is pronounced "mah-day"). A is pronounced "ah", E is pronounced "eh", I is pronounced 'iy', O is pronounced 'oh', and U is pronounced 'ew'. The only hard character for english speakers is 'R' (which luckily is absent here); it is pronounced halfway between an L and an R. Also, some times sylables are pronounced rather quickly so that they aren't that noticable - for example, watakushi ('I', polite) is pronounced like "watakshi")
