light map photon map, load save both please help

hi I am trying to sort what path to use for what purpose
could some one shed some light on the correct work flow for say a exterior animation with only camera moving...
my guess is it would be lightmap, shared and load... but if the camera flys to the other side of the building(hidden face to frame 0 of animation) it should be both, wrong?
If this is the case what is the correct way to save the initial gi solution. is photon estimate enough? to you have to use photon mapping....
also i read somewhere that if you choose photon map(as opposed to light map) in this situation you shoot all photons required hence requiring less fg rays at render time. Does this means that it will render the entire sequence faster at the cost of the first frame being slower??? Or is my understanding off...
finally what is cache irradiance exactly do?
forgive my multi question post
