1) "Torrential Tribute" must be activated before "Ceasefire".

2) You would lose the duel. You take 500 damage immediately, and since "Giant Germ" won't inflict damage until it is sent to the Graveyard, your opponent will never take the damage because he/she has already won.

3) Trap Cards (like "Dust Tornado") can be Chained to the activation of "Premature Burial" to destroy it and cancel its effect, even if "Jinzo" was targeted.
